+This is the source code repository for ERFA (Essential Routines for 
+Fundamental Astronomy).  ERFA is a C library containing key algorithms for 
+astronomy, and is based on the `SOFA library <http://www.iausofa.org/>`_ published by the International 
+Astronomical Union (IAU).  
+
+ERFA is intended to replicate the functionality of SOFA (aside from possible
+bugfixes in ERFA that have not yet been included in SOFA), but is licensed
+under a three-clause BSD license to enable its compatibility with a wide 
+range of open source licenses. Permission for this release has been
+obtained from the SOFA board, and is avilable in the ``LICENSE`` file included
+in this source distribution.
+
+Differences from SOFA
+---------------------
+
+This version of ERFA (v0.0.1) is based on SOFA version "20120301_a", with the 
+differences outlined below.
+
+ERFA Branding
+^^^^^^^^^^^^^
+
+All references to "SOFA" in the source code have been changed to ERFA, and 
+functions have the prefix ``era`` instead of ``iau``. 
+
+Building and Installing ERFA
+----------------------------
+
+To build and install a released version of ERFA in your OS's standard 
+location, simply do::
+
+    ./configure
+    make
+    make install
+
+For Developers
+^^^^^^^^^^^^^^
+
+If you are using a developer version from github, you will need to first do
+``./bootstrap.sh`` before the above commands.
+
+If you wish to build against the ERFA static library without installing, you
+will find it in ``$ERFAROOT/src/.libs/liberfa.a`` after running ``make``.
+

+
+Instructions for Doing A Release of ERFA
+========================================
+
+* Clone the ERFA repository from github (if you haven't already done so),
+  and change to the ERFA directory.
+
+* Make sure you are on the "master" branch from the "liberfa" github 
+  repository and have the latest version (if you have a fresh clone, this
+  should already be the case).
+
+* Update the version number in the `AC_INIT` macro of `configure.ac` to
+  the version number you are about to release, and also update the version 
+  mentioned in `README.rst`. 
+
+* Commit these changes using ``git commit``, with a commit message like 
+  ``Preparing release v0.0.1``.
+
+* Run `./bootstrap.sh`: you need `automake`, `autoconf` and `libtool` 
+  installed.  If no errors appear, this will create a new `./configure`
+  file.
+
+* Run `./configure`, which should create a `Makefile` in the top level 
+  directory and in ./src
+
+* Run `make check`, which will build the library and run the tests -
+  make sure they pass before proceeding.
+
+* Run `make distcheck`: this creates the distribution tarball, 
+  unpackages it and runs the check inside the untarred directory.
+  The resulting tarball will be named e.g., `erfa-0.0.1.tar.gz` and
+  will be placed in the working directory.
+
+* Tag the current commit with the version number (e.g., ``git tag v0.0.1``).  
+
+* Push up your changes and the new tag to github: 
+  ``git push --tags origin master``. (The command here assumes the git remote
+  "origin" points to the "liberfa/erfa" repository.  If not, substitute the
+  appropriate name.)
+
+* Go to the "liberfa/erfa" repository for the github page, and click on the
+  "releases" button, and then the release corresponding to the tag you just 
+  made. 
+
+* Click on the "Draft release notes or downloads".  Leave the title and
+  description blank (the release notes should be in the ``README.rst``),
+  but upload the tarball you created (e.g., `erfa-0.0.1.tar.gz`) by 
+  dropping it in the area that says "Attach binaries for this release 
+  by dropping them here." Click the "Publish release" button.

+**
+**  Notes:
+**
+**  1) The frame bias corrections in longitude and obliquity (radians)
+**     are required in order to correct for the offset between the GCRS
+**     pole and the mean J2000.0 pole.  They define, with respect to the
+**     GCRS frame, a J2000.0 mean pole that is consistent with the rest
+**     of the IAU 2000A precession-nutation model.
+**
+**  2) In addition to the displacement of the pole, the complete
+**     description of the frame bias requires also an offset in right
+**     ascension.  This is not part of the IAU 2000A model, and is from
+**     Chapront et al. (2002).  It is returned in radians.
+**
+**  3) This is a supplemented implementation of one aspect of the IAU
+**     2000A nutation model, formally adopted by the IAU General
+**     Assembly in 2000, namely MHB2000 (Mathews et al. 2002).

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,

+**
+**     The JD method is the most natural and convenient to use in

+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The matrix rb transforms vectors from GCRS to mean J2000.0 by
+**     applying frame bias.
+**
+**  3) The matrix rp transforms vectors from J2000.0 mean equator and
+**     equinox to mean equator and equinox of date by applying
+**     precession.
+**
+**  4) The matrix rbp transforms vectors from GCRS to mean equator and
+**     equinox of date by applying frame bias then precession.  It is
+**     the product rp x rb.

+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The matrix rc2i is the first stage in the transformation from

+**
+**  Returned:
+**     rc2i        double[3][3] celestial-to-intermediate matrix (Note 3)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The matrix rbpn transforms vectors from GCRS to true equator (and
+**     CIO or equinox) of date.  Only the CIP (bottom row) is used.
+**
+**  3) The matrix rc2i is the first stage in the transformation from
+**     celestial to terrestrial coordinates:
+**
+**        [TRS] = RPOM * R_3(ERA) * rc2i * [CRS]
+**
+**              = RC2T * [CRS]
+**
+**     where [CRS] is a vector in the Geocentric Celestial Reference
+**     System and [TRS] is a vector in the International Terrestrial
+**     Reference System (see IERS Conventions 2003), ERA is the Earth
+**     Rotation Angle and RPOM is the polar motion matrix.
+**
+**  4) Although its name does not include "00", This function is in fact
+**     specific to the IAU 2000 models.

+**     uta,utb  double         UT1 as a 2-part Julian Date (Note 1)

+**
+**  Returned:
+**     rc2t     double[3][3]   celestial-to-terrestrial matrix (Note 3)
+**
+**  Notes:
+**
+**  1) The TT and UT1 dates tta+ttb and uta+utb are Julian Dates,
+**     apportioned in any convenient way between the arguments uta and
+**     utb.  For example, JD(UT1)=2450123.7 could be expressed in any of
+**     these ways, among others:
+**
+**             uta            utb
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution is
+**     acceptable.  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  In the case of uta,utb, the
+**     date & time method is best matched to the Earth rotation angle
+**     algorithm used:  maximum precision is delivered when the uta
+**     argument is for 0hrs UT1 on the day in question and the utb
+**     argument lies in the range 0 to 1, or vice versa.
+**
+**  2) The arguments xp and yp are the coordinates (in radians) of the
+**     Celestial Intermediate Pole with respect to the International
+**     Terrestrial Reference System (see IERS Conventions 2003),
+**     measured along the meridians to 0 and 90 deg west respectively.
+**
+**  3) The matrix rc2t transforms from celestial to terrestrial
+**     coordinates:
+**
+**        [TRS] = RPOM * R_3(ERA) * RC2I * [CRS]
+**
+**              = rc2t * [CRS]
+**
+**     where [CRS] is a vector in the Geocentric Celestial Reference
+**     System and [TRS] is a vector in the International Terrestrial
+**     Reference System (see IERS Conventions 2003), RC2I is the
+**     celestial-to-intermediate matrix, ERA is the Earth rotation
+**     angle and RPOM is the polar motion matrix.
+**
+**  4) A faster, but slightly less accurate result (about 1 mas), can
+**     be obtained by using instead the eraC2t00b function.

+**
+**  Notes:
+**
+**  1) The TT and UT1 dates tta+ttb and uta+utb are Julian Dates,
+**     apportioned in any convenient way between the arguments uta and
+**     utb.  For example, JD(UT1)=2450123.7 could be expressed in any of
+**     these ways, among others:
+**
+**             uta            utb
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution is
+**     acceptable.  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  In the case of uta,utb, the
+**     date & time method is best matched to the Earth rotation angle
+**     algorithm used:  maximum precision is delivered when the uta
+**     argument is for 0hrs UT1 on the day in question and the utb
+**     argument lies in the range 0 to 1, or vice versa.
+**
+**  2) The caller is responsible for providing the nutation components;
+**     they are in longitude and obliquity, in radians and are with
+**     respect to the equinox and ecliptic of date.  For high-accuracy
+**     applications, free core nutation should be included as well as
+**     any other relevant corrections to the position of the CIP.
+**
+**  3) The arguments xp and yp are the coordinates (in radians) of the
+**     Celestial Intermediate Pole with respect to the International
+**     Terrestrial Reference System (see IERS Conventions 2003),
+**     measured along the meridians to 0 and 90 deg west respectively.
+**
+**  4) The matrix rc2t transforms from celestial to terrestrial
+**     coordinates:
+**
+**        [TRS] = RPOM * R_3(GST) * RBPN * [CRS]
+**
+**              = rc2t * [CRS]
+**
+**     where [CRS] is a vector in the Geocentric Celestial Reference
+**     System and [TRS] is a vector in the International Terrestrial
+**     Reference System (see IERS Conventions 2003), RBPN is the
+**     bias-precession-nutation matrix, GST is the Greenwich (apparent)
+**     Sidereal Time and RPOM is the polar motion matrix.
+**

+**     specific to the IAU 2000 models.

+**     date & time method is best matched to the Earth rotation angle
+**     algorithm used:  maximum precision is delivered when the uta
+**     argument is for 0hrs UT1 on the day in question and the utb
+**     argument lies in the range 0 to 1, or vice versa.
+**
+**  2) The Celestial Intermediate Pole coordinates are the x,y
+**     components of the unit vector in the Geocentric Celestial
+**     Reference System.
+**
+**  3) The arguments xp and yp are the coordinates (in radians) of the
+**     Celestial Intermediate Pole with respect to the International
+**     Terrestrial Reference System (see IERS Conventions 2003),
+**     measured along the meridians to 0 and 90 deg west respectively.
+**
+**  4) The matrix rc2t transforms from celestial to terrestrial
+**     coordinates:
+**
+**        [TRS] = RPOM * R_3(ERA) * RC2I * [CRS]
+**
+**              = rc2t * [CRS]
+**
+**     where [CRS] is a vector in the Geocentric Celestial Reference
+**     System and [TRS] is a vector in the International Terrestrial
+**     Reference System (see IERS Conventions 2003), ERA is the Earth
+**     Rotation Angle and RPOM is the polar motion matrix.
+**
+**  5) Although its name does not include "00", This function is in fact
+**     specific to the IAU 2000 models.

+**     scale     char[]  time scale ID (Note 1)
+**     ndp       int     resolution (Note 2)
+**     d1,d2     double  time as a 2-part Julian Date (Notes 3,4)
+**
+**  Returned:
+**     iy,im,id  int     year, month, day in Gregorian calendar (Note 5)
+**     ihmsf     int[4]  hours, minutes, seconds, fraction (Note 1)
+**
+**  Returned (function value):

+**                                0 = OK
+**                               -1 = unacceptable date (Note 6)
+**
+**  Notes:
+**
+**  1) scale identifies the time scale.  Only the value "UTC" (in upper
+**     case) is significant, and enables handling of leap seconds (see
+**     Note 4).
+**
+**  2) ndp is the number of decimal places in the seconds field, and can
+**     have negative as well as positive values, such as:
+**
+**     ndp         resolution
+**     -4            1 00 00
+**     -3            0 10 00
+**     -2            0 01 00
+**     -1            0 00 10
+**      0            0 00 01
+**      1            0 00 00.1
+**      2            0 00 00.01
+**      3            0 00 00.001
+**
+**     The limits are platform dependent, but a safe range is -5 to +9.
+**
+**  3) d1+d2 is Julian Date, apportioned in any convenient way between
+**     the two arguments, for example where d1 is the Julian Day Number
+**     and d2 is the fraction of a day.  In the case of UTC, where the
+**     use of JD is problematical, special conventions apply:  see the
+**     next note.
+**
+**  4) JD cannot unambiguously represent UTC during a leap second unless
+**     special measures are taken.  The ERFA internal convention is that
+**     the quasi-JD day represents UTC days whether the length is 86399,
+**     86400 or 86401 SI seconds.
+**
+**  5) The warning status "dubious year" flags UTCs that predate the
+**     introduction of the time scale and that are too far in the future
+**     to be trusted.  See eraDat for further details.
+**
+**  6) For calendar conventions and limitations, see eraCal2jd.

+**     ihmsf   int[4]  hours, minutes, seconds, fraction
+**
+**  Notes:
+**
+**  1) The argument ndp is interpreted as follows:
+**
+**     ndp         resolution
+**      :      ...0000 00 00
+**     -7         1000 00 00
+**     -6          100 00 00
+**     -5           10 00 00
+**     -4            1 00 00
+**     -3            0 10 00
+**     -2            0 01 00
+**     -1            0 00 10
+**      0            0 00 01
+**      1            0 00 00.1
+**      2            0 00 00.01
+**      3            0 00 00.001
+**      :            0 00 00.000...
+**
+**  2) The largest positive useful value for ndp is determined by the
+**     size of days, the format of double on the target platform, and
+**     the risk of overflowing ihmsf[3].  On a typical platform, for
+**     days up to 1.0, the available floating-point precision might
+**     correspond to ndp=12.  However, the practical limit is typically
+**     ndp=9, set by the capacity of a 32-bit int, or ndp=4 if int is
+**     only 16 bits.
+**
+**  3) The absolute value of days may exceed 1.0.  In cases where it
+**     does not, it is up to the caller to test for and handle the
+**     case where days is very nearly 1.0 and rounds up to 24 hours,
+**     by testing for ihmsf[0]=24 and setting ihmsf[0-3] to zero.

+**  Given:

+**     im     int            month (Note 2)
+**     id     int            day (Notes 2 and 3)

+**  Returned (function value):
+**            int      status (Note 5):
+**                       1 = dubious year (Note 1)
+**                       0 = OK
+**                      -1 = bad year

+**                      -3 = bad day (Note 3)
+**                      -4 = bad fraction (Note 4)
+**
+**  Notes:
+**
+**  1) UTC began at 1960 January 1.0 (JD 2436934.5) and it is improper
+**     to call the function with an earlier date.  If this is attempted,
+**     zero is returned together with a warning status.
+**
+**     Because leap seconds cannot, in principle, be predicted in
+**     advance, a reliable check for dates beyond the valid range is
+**     impossible.  To guard against gross errors, a year five or more
+**     after the release year of the present function (see parameter
+**     IYV) is considered dubious.  In this case a warning status is
+**     returned but the result is computed in the normal way.
+**
+**     For both too-early and too-late years, the warning status is
+**     j=+1.  This is distinct from the error status j=-1, which
+**     signifies a year so early that JD could not be computed.
+**
+**  2) If the specified date is for a day which ends with a leap second,
+**     the UTC-TAI value returned is for the period leading up to the
+**     leap second.  If the date is for a day which begins as a leap
+**     second ends, the UTC-TAI returned is for the period following the
+**     leap second.
+**
+**  3) The day number must be in the normal calendar range, for example
+**     1 through 30 for April.  The "almanac" convention of allowing
+**     such dates as January 0 and December 32 is not supported in this
+**     function, in order to avoid confusion near leap seconds.
+**
+**  4) The fraction of day is used only for dates before the
+**     introduction of leap seconds, the first of which occurred at the
+**     end of 1971.  It is tested for validity (0 to 1 is the valid
+**     range) even if not used;  if invalid, zero is used and status
+**     j=-4 is returned.  For many applications, setting fd to zero is
+**     acceptable;  the resulting error is always less than 3 ms (and
+**     occurs only pre-1972).
+**
+**  5) The status value returned in the case where there are multiple
+**     errors refers to the first error detected.  For example, if the
+**     month and day are 13 and 32 respectively, j=-2 (bad month)
+**     will be returned.
+**
+**  6) In cases where a valid result is not available, zero is returned.
+**
+**  References:
+**
+**  1) For dates from 1961 January 1 onwards, the expressions from the

+**
+**  An approximation to TDB-TT, the difference between barycentric
+**  dynamical time and terrestrial time, for an observer on the Earth.
+**
+**  The different time scales - proper, coordinate and realized - are
+**  related to each other:
+**
+**            TAI             <-  physically realized
+**             :

+**             :

+**             :
+**    rate adjustment (L_G)   <-  definition of TT
+**             :
+**            TCG             <-  time scale for GCRS
+**             :
+**      "periodic" terms      <-  eraDtdb  is an implementation
+**             :
+**    rate adjustment (L_C)   <-  function of solar-system ephemeris
+**             :
+**            TCB             <-  time scale for BCRS
+**             :
+**    rate adjustment (-L_B)  <-  definition of TDB
+**             :
+**            TDB             <-  TCB scaled to track TT
+**             :
+**      "periodic" terms      <-  -eraDtdb is an approximation
+**             :
+**            TT              <-  terrestrial time
+**
+**  Adopted values for the various constants can be found in the IERS
+**  Conventions (McCarthy & Petit 2003).
+**
+**  Given:
+**     date1,date2   double  date, TDB (Notes 1-3)
+**     ut            double  universal time (UT1, fraction of one day)
+**     elong         double  longitude (east positive, radians)
+**     u             double  distance from Earth spin axis (km)
+**     v             double  distance north of equatorial plane (km)
+**
+**  Returned (function value):
+**                   double  TDB-TT (seconds)
+**
+**  Notes:
+**
+**  1) The date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**     Although the date is, formally, barycentric dynamical time (TDB),
+**     the terrestrial dynamical time (TT) can be used with no practical
+**     effect on the accuracy of the prediction.
+**
+**  2) TT can be regarded as a coordinate time that is realized as an
+**     offset of 32.184s from International Atomic Time, TAI.  TT is a
+**     specific linear transformation of geocentric coordinate time TCG,
+**     which is the time scale for the Geocentric Celestial Reference
+**     System, GCRS.
+**
+**  3) TDB is a coordinate time, and is a specific linear transformation
+**     of barycentric coordinate time TCB, which is the time scale for
+**     the Barycentric Celestial Reference System, BCRS.
+**
+**  4) The difference TCG-TCB depends on the masses and positions of the
+**     bodies of the solar system and the velocity of the Earth.  It is
+**     dominated by a rate difference, the residual being of a periodic
+**     character.  The latter, which is modeled by the present function,
+**     comprises a main (annual) sinusoidal term of amplitude
+**     approximately 0.00166 seconds, plus planetary terms up to about
+**     20 microseconds, and lunar and diurnal terms up to 2 microseconds.
+**     These effects come from the changing transverse Doppler effect
+**     and gravitational red-shift as the observer (on the Earth's
+**     surface) experiences variations in speed (with respect to the
+**     BCRS) and gravitational potential.
+**
+**  5) TDB can be regarded as the same as TCB but with a rate adjustment
+**     to keep it close to TT, which is convenient for many applications.
+**     The history of successive attempts to define TDB is set out in
+**     Resolution 3 adopted by the IAU General Assembly in 2006, which
+**     defines a fixed TDB(TCB) transformation that is consistent with
+**     contemporary solar-system ephemerides.  Future ephemerides will
+**     imply slightly changed transformations between TCG and TCB, which
+**     could introduce a linear drift between TDB and TT;  however, any
+**     such drift is unlikely to exceed 1 nanosecond per century.
+**
+**  6) The geocentric TDB-TT model used in the present function is that of
+**     Fairhead & Bretagnon (1990), in its full form.  It was originally
+**     supplied by Fairhead (private communications with P.T.Wallace,
+**     1990) as a Fortran subroutine.  The present C function contains an
+**     adaptation of the Fairhead code.  The numerical results are
+**     essentially unaffected by the changes, the differences with
+**     respect to the Fairhead & Bretagnon original being at the 1e-20 s
+**     level.
+**
+**     The topocentric part of the model is from Moyer (1981) and
+**     Murray (1983), with fundamental arguments adapted from
+**     Simon et al. 1994.  It is an approximation to the expression
+**     ( v / c ) . ( r / c ), where v is the barycentric velocity of
+**     the Earth, r is the geocentric position of the observer and
+**     c is the speed of light.
+**
+**     By supplying zeroes for u and v, the topocentric part of the
+**     model can be nullified, and the function will return the Fairhead
+**     & Bretagnon result alone.
+**
+**  7) During the interval 1950-2050, the absolute accuracy is better
+**     than +/- 3 nanoseconds relative to time ephemerides obtained by
+**     direct numerical integrations based on the JPL DE405 solar system
+**     ephemeris.
+**
+**  8) It must be stressed that the present function is merely a model,
+**     and that numerical integration of solar-system ephemerides is the
+**     definitive method for predicting the relationship between TCG and
+**     TCB and hence between TT and TDB.

+**                               -6 = bad second (<0)
+**
+**  Notes:
+**
+**  1) scale identifies the time scale.  Only the value "UTC" (in upper
+**     case) is significant, and enables handling of leap seconds (see
+**     Note 4).
+**
+**  2) For calendar conventions and limitations, see eraCal2jd.
+**
+**  3) The sum of the results, d1+d2, is Julian Date, where normally d1
+**     is the Julian Day Number and d2 is the fraction of a day.  In the
+**     case of UTC, where the use of JD is problematical, special
+**     conventions apply:  see the next note.
+**
+**  4) JD cannot unambiguously represent UTC during a leap second unless
+**     special measures are taken.  The ERFA internal convention is that
+**     the quasi-JD day represents UTC days whether the length is 86399,
+**     86400 or 86401 SI seconds.
+**
+**  5) The warning status "time is after end of day" usually means that
+**     the sec argument is greater than 60.0.  However, in a day ending
+**     in a leap second the limit changes to 61.0 (or 59.0 in the case
+**     of a negative leap second).
+**
+**  6) The warning status "dubious year" flags UTCs that predate the
+**     introduction of the time scale and that are too far in the future
+**     to be trusted.  See eraDat for further details.
+**
+**  7) Only in the case of continuous and regular time scales (TAI, TT,
+**     TCG, TCB and TDB) is the result d1+d2 a Julian Date, strictly
+**     speaking.  In the other cases (UT1 and UTC) the result must be
+**     used with circumspection;  in particular the difference between
+**     two such results cannot be interpreted as a precise time
+**     interval.

+**  Equation of the equinoxes, compatible with IAU 2000 resolutions but
+**  using the truncated nutation model IAU 2000B.

+**     date1,date2  double    TT as a 2-part Julian Date (Note 1)

+**  Returned (function value):
+**                  double    equation of the equinoxes (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The result, which is in radians, operates in the following sense:
+**
+**        Greenwich apparent ST = GMST + equation of the equinoxes
+**
+**  3) The result is compatible with the IAU 2000 resolutions except
+**     that accuracy has been compromised for the sake of speed.  For
+**     further details, see McCarthy & Luzum (2001), IERS Conventions
+**     2003 and Capitaine et al. (2003).

+**
+**  2) The "complementary terms" are part of the equation of the
+**     equinoxes (EE), classically the difference between apparent and
+**     mean Sidereal Time:
+**
+**        GAST = GMST + EE
+**
+**     with:
+**
+**        EE = dpsi * cos(eps)
+**
+**     where dpsi is the nutation in longitude and eps is the obliquity
+**     of date.  However, if the rotation of the Earth were constant in
+**     an inertial frame the classical formulation would lead to
+**     apparent irregularities in the UT1 timescale traceable to side-
+**     effects of precession-nutation.  In order to eliminate these
+**     effects from UT1, "complementary terms" were introduced in 1994
+**     (IAU, 1994) and took effect from 1997 (Capitaine and Gontier,
+**     1993):
+**
+**        GAST = GMST + CT + EE
+**
+**     By convention, the complementary terms are included as part of
+**     the equation of the equinoxes rather than as part of the mean
+**     Sidereal Time.  This slightly compromises the "geometrical"
+**     interpretation of mean sidereal time but is otherwise
+**     inconsequential.
+**
+**     The present function computes CT in the above expression,
+**     compatible with IAU 2000 resolutions (Capitaine et al., 2002, and
+**     IERS Conventions 2003).

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The equation of the origins is the distance between the true
+**     equinox and the celestial intermediate origin and, equivalently,
+**     the difference between Earth rotation angle and Greenwich
+**     apparent sidereal time (ERA-GST).  It comprises the precession
+**     (since J2000.0) in right ascension plus the equation of the

+**
+**  Notes:
+**
+**  1) The TDB date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TDB)=2450123.7 could be expressed in any of these ways, among
+**     others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in cases
+**     where the loss of several decimal digits of resolution is
+**     acceptable.  The J2000 method is best matched to the way the
+**     argument is handled internally and will deliver the optimum
+**     resolution.  The MJD method and the date & time methods are both
+**     good compromises between resolution and convenience.  However,
+**     the accuracy of the result is more likely to be limited by the
+**     algorithm itself than the way the date has been expressed.
+**
+**     n.b. TT can be used instead of TDB in most applications.
+**
+**  2) On return, the arrays pvh and pvb contain the following:
+**
+**        pvh[0][0]  x       }
+**        pvh[0][1]  y       } heliocentric position, AU
+**        pvh[0][2]  z       }
+**
+**        pvh[1][0]  xdot    }
+**        pvh[1][1]  ydot    } heliocentric velocity, AU/d
+**        pvh[1][2]  zdot    }
+**
+**        pvb[0][0]  x       }
+**        pvb[0][1]  y       } barycentric position, AU
+**        pvb[0][2]  z       }
+**
+**        pvb[1][0]  xdot    }
+**        pvb[1][1]  ydot    } barycentric velocity, AU/d
+**        pvb[1][2]  zdot    }
+**
+**     The vectors are with respect to the Barycentric Celestial
+**     Reference System.  The time unit is one day in TDB.
+**
+**  3) The function is a SIMPLIFIED SOLUTION from the planetary theory
+**     VSOP2000 (X. Moisson, P. Bretagnon, 2001, Celes. Mechanics &
+**     Dyn. Astron., 80, 3/4, 205-213) and is an adaptation of original
+**     Fortran code supplied by P. Bretagnon (private comm., 2000).
+**
+**  4) Comparisons over the time span 1900-2100 with this simplified
+**     solution and the JPL DE405 ephemeris give the following results:
+**
+**                                RMS    max
+**           Heliocentric:
+**              position error    3.7   11.2   km
+**              velocity error    1.4    5.0   mm/s
+**
+**           Barycentric:
+**              position error    4.6   13.4   km
+**              velocity error    1.4    4.9   mm/s
+**
+**     Comparisons with the JPL DE406 ephemeris show that by 1800 and
+**     2200 the position errors are approximately double their 1900-2100
+**     size.  By 1500 and 2500 the deterioration is a factor of 10 and
+**     by 1000 and 3000 a factor of 60.  The velocity accuracy falls off
+**     at about half that rate.
+**
+**  5) It is permissible to use the same array for pvh and pvb, which
+**     will receive the barycentric values.

+** Ephemeris Coefficients
+** ----------------------
+**
+** The ephemeris consists of harmonic terms for predicting (i) the Sun
+** to Earth vector and (ii) the Solar-System-barycenter to Sun vector
+** respectively.  The coefficients are stored in arrays which, although
+** 1-demensional, contain groups of three.  Each triplet of
+** coefficients is the amplitude, phase and frequency for one term in
+** the model, and each array contains the number of terms called for by
+** the model.
+**
+** There are eighteen such arrays, named as follows:

+**
+**  Notes:
+**
+**  1) The date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**

+**
+**  Notes:
+**
+**  1) The UT1 date dj1+dj2 is a Julian Date, apportioned in any
+**     convenient way between the arguments dj1 and dj2.  For example,
+**     JD(UT1)=2450123.7 could be expressed in any of these ways,

+**         2450123.7           0.0       (JD method)

+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  The date & time method is
+**     best matched to the algorithm used:  maximum precision is
+**     delivered when the dj1 argument is for 0hrs UT1 on the day in
+**     question and the dj2 argument lies in the range 0 to 1, or vice
+**     versa.
+**
+**  2) The algorithm is adapted from Expression 22 of Capitaine et al.
+**     2000.  The time argument has been expressed in days directly,
+**     and, to retain precision, integer contributions have been
+**     eliminated.  The same formulation is given in IERS Conventions

+**  Transform an FK5 (J2000.0) star position into the system of the

+**     r5           double   FK5 RA (radians), equinox J2000.0, at date
+**     d5           double   FK5 Dec (radians), equinox J2000.0, at date

+**  Returned:
+**     rh           double   Hipparcos RA (radians)
+**     dh           double   Hipparcos Dec (radians)
+**
+**  Notes:
+**
+**  1) This function converts a star position from the FK5 system to
+**     the Hipparcos system, in such a way that the Hipparcos proper
+**     motion is zero.  Because such a star has, in general, a non-zero
+**     proper motion in the FK5 system, the function requires the date
+**     at which the position in the FK5 system was determined.
+**
+**  2) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  3) The FK5 to Hipparcos transformation is modeled as a pure
+**     rotation and spin;  zonal errors in the FK5 catalogue are not
+**     taken into account.
+**
+**  4) The position returned by this function is in the Hipparcos
+**     reference system but at date date1+date2.

+**  Transform geodetic coordinates to geocentric for a reference
+**  ellipsoid of specified form.
+**
+**  Given:
+**     a       double     equatorial radius (Notes 1,4)
+**     f       double     flattening (Notes 2,4)
+**     elong   double     longitude (radians, east +ve)
+**     phi     double     latitude (geodetic, radians, Note 4)
+**     height  double     height above ellipsoid (geodetic, Notes 3,4)
+**
+**  Returned:
+**     xyz     double[3]  geocentric vector (Note 3)
+**
+**  Returned (function value):
+**             int        status:  0 = OK
+**                                -1 = illegal case (Note 4)
+**  Notes:
+**
+**  1) The equatorial radius, a, can be in any units, but meters is
+**     the conventional choice.
+**
+**  2) The flattening, f, is (for the Earth) a value around 0.00335,
+**     i.e. around 1/298.
+**
+**  3) The equatorial radius, a, and the height, height, must be
+**     given in the same units, and determine the units of the
+**     returned geocentric vector, xyz.
+**
+**  4) No validation is performed on individual arguments.  The error
+**     status -1 protects against (unrealistic) cases that would lead
+**     to arithmetic exceptions.  If an error occurs, xyz is unchanged.
+**
+**  5) The inverse transformation is performed in the function
+**     eraGc2gde.
+**
+**  6) The transformation for a standard ellipsoid (such as WGS84) can
+**     more conveniently be performed by calling eraGd2gc,  which uses a
+**     numerical code to identify the required a and f values.

+**  Greenwich mean sidereal time (model consistent with IAU 2000
+**  resolutions).
+**
+**  Given:
+**     uta,utb    double    UT1 as a 2-part Julian Date (Notes 1,2)
+**     tta,ttb    double    TT as a 2-part Julian Date (Notes 1,2)
+**
+**  Returned (function value):
+**                double    Greenwich mean sidereal time (radians)
+**
+**  Notes:
+**
+**  1) The UT1 and TT dates uta+utb and tta+ttb respectively, are both
+**     Julian Dates, apportioned in any convenient way between the
+**     argument pairs.  For example, JD=2450123.7 could be expressed in
+**     any of these ways, among others:
+**
+**            Part A         Part B
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable (in the case of UT;  the TT is not at all critical
+**     in this respect).  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  For UT, the date & time
+**     method is best matched to the algorithm that is used by the Earth
+**     Rotation Angle function, called internally:  maximum precision is
+**     delivered when the uta argument is for 0hrs UT1 on the day in
+**     question and the utb argument lies in the range 0 to 1, or vice
+**     versa.
+**
+**  2) Both UT1 and TT are required, UT1 to predict the Earth rotation
+**     and TT to predict the effects of precession.  If UT1 is used for
+**     both purposes, errors of order 100 microarcseconds result.
+**
+**  3) This GMST is compatible with the IAU 2000 resolutions and must be
+**     used only in conjunction with other IAU 2000 compatible
+**     components such as precession-nutation and equation of the
+**     equinoxes.
+**
+**  4) The result is returned in the range 0 to 2pi.
+**
+**  5) The algorithm is from Capitaine et al. (2003) and IERS
+**     Conventions 2003.

+**  Universal Time to Greenwich mean sidereal time (IAU 1982 model).

+**
+**  Returned (function value):
+**                double    Greenwich mean sidereal time (radians)
+**
+**  Notes:
+**
+**  1) The UT1 date dj1+dj2 is a Julian Date, apportioned in any
+**     convenient way between the arguments dj1 and dj2.  For example,
+**     JD(UT1)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**             dj1            dj2
+**
+**         2450123.7D0        0D0        (JD method)
+**          2451545D0      -1421.3D0     (J2000 method)
+**         2400000.5D0     50123.2D0     (MJD method)
+**         2450123.5D0       0.2D0       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  The date & time method is
+**     best matched to the algorithm used:  maximum accuracy (or, at
+**     least, minimum noise) is delivered when the dj1 argument is for
+**     0hrs UT1 on the day in question and the dj2 argument lies in the
+**     range 0 to 1, or vice versa.
+**
+**  2) The algorithm is based on the IAU 1982 expression.  This is
+**     always described as giving the GMST at 0 hours UT1.  In fact, it
+**     gives the difference between the GMST and the UT, the steady
+**     4-minutes-per-day drawing-ahead of ST with respect to UT.  When
+**     whole days are ignored, the expression happens to equal the GMST
+**     at 0 hours UT1 each day.
+**
+**  3) In this function, the entire UT1 (the sum of the two arguments
+**     dj1 and dj2) is used directly as the argument for the standard
+**     formula, the constant term of which is adjusted by 12 hours to
+**     take account of the noon phasing of Julian Date.  The UT1 is then
+**     added, but omitting whole days to conserve accuracy.

+**  Greenwich apparent sidereal time (consistent with IAU 2000
+**  resolutions).

+**     uta,utb    double    UT1 as a 2-part Julian Date (Notes 1,2)
+**     tta,ttb    double    TT as a 2-part Julian Date (Notes 1,2)
+**
+**  Returned (function value):
+**                double    Greenwich apparent sidereal time (radians)
+**
+**  Notes:
+**
+**  1) The UT1 and TT dates uta+utb and tta+ttb respectively, are both
+**     Julian Dates, apportioned in any convenient way between the
+**     argument pairs.  For example, JD=2450123.7 could be expressed in
+**     any of these ways, among others:
+**
+**            Part A        Part B
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable (in the case of UT;  the TT is not at all critical
+**     in this respect).  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  For UT, the date & time
+**     method is best matched to the algorithm that is used by the Earth
+**     Rotation Angle function, called internally:  maximum precision is
+**     delivered when the uta argument is for 0hrs UT1 on the day in
+**     question and the utb argument lies in the range 0 to 1, or vice
+**     versa.
+**
+**  2) Both UT1 and TT are required, UT1 to predict the Earth rotation
+**     and TT to predict the effects of precession-nutation.  If UT1 is
+**     used for both purposes, errors of order 100 microarcseconds
+**     result.
+**
+**  3) This GAST is compatible with the IAU 2000 resolutions and must be
+**     used only in conjunction with other IAU 2000 compatible
+**     components such as precession-nutation.
+**
+**  4) The result is returned in the range 0 to 2pi.
+**
+**  5) The algorithm is from Capitaine et al. (2003) and IERS
+**     Conventions 2003.

+**  Greenwich apparent sidereal time (consistent with IAU 2000 and 2006
+**  resolutions).
+**
+**  Given:
+**     uta,utb    double    UT1 as a 2-part Julian Date (Notes 1,2)
+**     tta,ttb    double    TT as a 2-part Julian Date (Notes 1,2)
+**
+**  Returned (function value):
+**                double    Greenwich apparent sidereal time (radians)
+**
+**  Notes:
+**
+**  1) The UT1 and TT dates uta+utb and tta+ttb respectively, are both
+**     Julian Dates, apportioned in any convenient way between the
+**     argument pairs.  For example, JD=2450123.7 could be expressed in
+**     any of these ways, among others:
+**
+**            Part A        Part B
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable (in the case of UT;  the TT is not at all critical
+**     in this respect).  The J2000 and MJD methods are good compromises
+**     between resolution and convenience.  For UT, the date & time
+**     method is best matched to the algorithm that is used by the Earth
+**     rotation angle function, called internally:  maximum precision is
+**     delivered when the uta argument is for 0hrs UT1 on the day in
+**     question and the utb argument lies in the range 0 to 1, or vice
+**     versa.
+**
+**  2) Both UT1 and TT are required, UT1 to predict the Earth rotation
+**     and TT to predict the effects of precession-nutation.  If UT1 is
+**     used for both purposes, errors of order 100 microarcseconds
+**     result.
+**
+**  3) This GAST is compatible with the IAU 2000/2006 resolutions and
+**     must be used only in conjunction with IAU 2006 precession and
+**     IAU 2000A nutation.
+**
+**  4) The result is returned in the range 0 to 2pi.

+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The proper motion in RA is dRA/dt rather than cos(Dec)*dRA/dt.
+**
+**  3) The FK5 to Hipparcos transformation is modeled as a pure rotation
+**     and spin;  zonal errors in the FK5 catalogue are not taken into
+**     account.
+**
+**  4) It was the intention that Hipparcos should be a close
+**     approximation to an inertial frame, so that distant objects have
+**     zero proper motion;  such objects have (in general) non-zero
+**     proper motion in FK5, and this function returns those fictitious
+**     proper motions.
+**
+**  5) The position returned by this function is in the FK5 J2000.0
+**     reference system but at date date1+date2.

+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**

+**  Nutation, IAU 2000A model (MHB2000 luni-solar and planetary nutation
+**  with free core nutation omitted).
+**
+**  Given:
+**     date1,date2   double   TT as a 2-part Julian Date (Note 1)
+**
+**  Returned:
+**     dpsi,deps     double   nutation, luni-solar + planetary (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The nutation components in longitude and obliquity are in radians
+**     and with respect to the equinox and ecliptic of date.  The
+**     obliquity at J2000.0 is assumed to be the Lieske et al. (1977)
+**     value of 84381.448 arcsec.
+**
+**     Both the luni-solar and planetary nutations are included.  The
+**     latter are due to direct planetary nutations and the
+**     perturbations of the lunar and terrestrial orbits.
+**
+**  3) The function computes the MHB2000 nutation series with the
+**     associated corrections for planetary nutations.  It is an
+**     implementation of the nutation part of the IAU 2000A precession-
+**     nutation model, formally adopted by the IAU General Assembly in
+**     2000, namely MHB2000 (Mathews et al. 2002), but with the free
+**     core nutation (FCN - see Note 4) omitted.
+**
+**  4) The full MHB2000 model also contains contributions to the
+**     nutations in longitude and obliquity due to the free-excitation
+**     of the free-core-nutation during the period 1979-2000.  These FCN
+**     terms, which are time-dependent and unpredictable, are NOT
+**     included in the present function and, if required, must be
+**     independently computed.  With the FCN corrections included, the
+**     present function delivers a pole which is at current epochs
+**     accurate to a few hundred microarcseconds.  The omission of FCN
+**     introduces further errors of about that size.
+**
+**  5) The present function provides classical nutation.  The MHB2000
+**     algorithm, from which it is adapted, deals also with (i) the
+**     offsets between the GCRS and mean poles and (ii) the adjustments
+**     in longitude and obliquity due to the changed precession rates.
+**     These additional functions, namely frame bias and precession
+**     adjustments, are supported by the ERFA functions eraBi00  and
+**     eraPr00.
+**
+**  6) The MHB2000 algorithm also provides "total" nutations, comprising
+**     the arithmetic sum of the frame bias, precession adjustments,
+**     luni-solar nutation and planetary nutation.  These total
+**     nutations can be used in combination with an existing IAU 1976
+**     precession implementation, such as eraPmat76,  to deliver GCRS-
+**     to-true predictions of sub-mas accuracy at current dates.
+**     However, there are three shortcomings in the MHB2000 model that
+**     must be taken into account if more accurate or definitive results
+**     are required (see Wallace 2002):
+**
+**       (i) The MHB2000 total nutations are simply arithmetic sums,
+**           yet in reality the various components are successive Euler
+**           rotations.  This slight lack of rigor leads to cross terms
+**           that exceed 1 mas after a century.  The rigorous procedure
+**           is to form the GCRS-to-true rotation matrix by applying the
+**           bias, precession and nutation in that order.
+**
+**      (ii) Although the precession adjustments are stated to be with
+**           respect to Lieske et al. (1977), the MHB2000 model does
+**           not specify which set of Euler angles are to be used and
+**           how the adjustments are to be applied.  The most literal
+**           and straightforward procedure is to adopt the 4-rotation
+**           epsilon_0, psi_A, omega_A, xi_A option, and to add DPSIPR
+**           to psi_A and DEPSPR to both omega_A and eps_A.
+**
+**     (iii) The MHB2000 model predates the determination by Chapront
+**           et al. (2002) of a 14.6 mas displacement between the
+**           J2000.0 mean equinox and the origin of the ICRS frame.  It
+**           should, however, be noted that neglecting this displacement
+**           when calculating star coordinates does not lead to a
+**           14.6 mas change in right ascension, only a small second-
+**           order distortion in the pattern of the precession-nutation
+**           effect.
+**
+**     For these reasons, the ERFA functions do not generate the "total
+**     nutations" directly, though they can of course easily be
+**     generated by calling eraBi00, eraPr00 and the present function
+**     and adding the results.
+**
+**  7) The MHB2000 model contains 41 instances where the same frequency
+**     appears multiple times, of which 38 are duplicates and three are
+**     triplicates.  To keep the present code close to the original MHB
+**     algorithm, this small inefficiency has not been corrected.

+**  Nutation, IAU 2000B model.
+**
+**  Given:
+**     date1,date2   double    TT as a 2-part Julian Date (Note 1)
+**
+**  Returned:
+**     dpsi,deps     double    nutation, luni-solar + planetary (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The nutation components in longitude and obliquity are in radians
+**     and with respect to the equinox and ecliptic of date.  The
+**     obliquity at J2000.0 is assumed to be the Lieske et al. (1977)
+**     value of 84381.448 arcsec.  (The errors that result from using
+**     this function with the IAU 2006 value of 84381.406 arcsec can be
+**     neglected.)
+**
+**     The nutation model consists only of luni-solar terms, but
+**     includes also a fixed offset which compensates for certain long-
+**     period planetary terms (Note 7).
+**
+**  3) This function is an implementation of the IAU 2000B abridged
+**     nutation model formally adopted by the IAU General Assembly in
+**     2000.  The function computes the MHB_2000_SHORT luni-solar
+**     nutation series (Luzum 2001), but without the associated
+**     corrections for the precession rate adjustments and the offset
+**     between the GCRS and J2000.0 mean poles.
+**
+**  4) The full IAU 2000A (MHB2000) nutation model contains nearly 1400
+**     terms.  The IAU 2000B model (McCarthy & Luzum 2003) contains only
+**     77 terms, plus additional simplifications, yet still delivers
+**     results of 1 mas accuracy at present epochs.  This combination of
+**     accuracy and size makes the IAU 2000B abridged nutation model
+**     suitable for most practical applications.
+**
+**     The function delivers a pole accurate to 1 mas from 1900 to 2100
+**     (usually better than 1 mas, very occasionally just outside
+**     1 mas).  The full IAU 2000A model, which is implemented in the
+**     function eraNut00a (q.v.), delivers considerably greater accuracy
+**     at current dates;  however, to realize this improved accuracy,
+**     corrections for the essentially unpredictable free-core-nutation
+**     (FCN) must also be included.
+**
+**  5) The present function provides classical nutation.  The
+**     MHB_2000_SHORT algorithm, from which it is adapted, deals also
+**     with (i) the offsets between the GCRS and mean poles and (ii) the
+**     adjustments in longitude and obliquity due to the changed
+**     precession rates.  These additional functions, namely frame bias
+**     and precession adjustments, are supported by the ERFA functions
+**     eraBi00  and eraPr00.
+**
+**  6) The MHB_2000_SHORT algorithm also provides "total" nutations,
+**     comprising the arithmetic sum of the frame bias, precession
+**     adjustments, and nutation (luni-solar + planetary).  These total
+**     nutations can be used in combination with an existing IAU 1976
+**     precession implementation, such as eraPmat76,  to deliver GCRS-
+**     to-true predictions of mas accuracy at current epochs.  However,
+**     for symmetry with the eraNut00a  function (q.v. for the reasons),
+**     the ERFA functions do not generate the "total nutations"
+**     directly.  Should they be required, they could of course easily
+**     be generated by calling eraBi00, eraPr00 and the present function
+**     and adding the results.
+**
+**  7) The IAU 2000B model includes "planetary bias" terms that are
+**     fixed in size but compensate for long-period nutations.  The
+**     amplitudes quoted in McCarthy & Luzum (2003), namely
+**     Dpsi = -1.5835 mas and Depsilon = +1.6339 mas, are optimized for
+**     the "total nutations" method described in Note 6.  The Luzum
+**     (2001) values used in this ERFA implementation, namely -0.135 mas
+**     and +0.388 mas, are optimized for the "rigorous" method, where
+**     frame bias, precession and nutation are applied separately and in
+**     that order.  During the interval 1995-2050, the ERFA
+**     implementation delivers a maximum error of 1.001 mas (not
+**     including FCN).

+**  IAU 2000A nutation with adjustments to match the IAU 2006
+**  precession.
+**
+**  Given:
+**     date1,date2   double   TT as a 2-part Julian Date (Note 1)
+**
+**  Returned:
+**     dpsi,deps     double   nutation, luni-solar + planetary (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The nutation components in longitude and obliquity are in radians
+**     and with respect to the mean equinox and ecliptic of date,
+**     IAU 2006 precession model (Hilton et al. 2006, Capitaine et al.
+**     2005).
+**
+**  3) The function first computes the IAU 2000A nutation, then applies
+**     adjustments for (i) the consequences of the change in obliquity
+**     from the IAU 1980 ecliptic to the IAU 2006 ecliptic and (ii) the
+**     secular variation in the Earth's dynamical form factor J2.
+**
+**  4) The present function provides classical nutation, complementing
+**     the IAU 2000 frame bias and IAU 2006 precession.  It delivers a
+**     pole which is at current epochs accurate to a few tens of
+**     microarcseconds, apart from the free core nutation.

+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The nutation components are with respect to the ecliptic of
+**     date.

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The matrix operates in the sense V(true) = rmatn * V(mean),
+**     where the p-vector V(true) is with respect to the true
+**     equatorial triad of date and the p-vector V(mean) is with

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) This function returns the set of equinox based angles for the
+**     Capitaine et al. "P03" precession theory, adopted by the IAU in
+**     2006.  The angles are set out in Table 1 of Hilton et al. (2006):
+**
+**     eps0   epsilon_0   obliquity at J2000.0
+**     psia   psi_A       luni-solar precession
+**     oma    omega_A     inclination of equator wrt J2000.0 ecliptic
+**     bpa    P_A         ecliptic pole x, J2000.0 ecliptic triad
+**     bqa    Q_A         ecliptic pole -y, J2000.0 ecliptic triad
+**     pia    pi_A        angle between moving and J2000.0 ecliptics
+**     bpia   Pi_A        longitude of ascending node of the ecliptic
+**     epsa   epsilon_A   obliquity of the ecliptic
+**     chia   chi_A       planetary precession
+**     za     z_A         equatorial precession: -3rd 323 Euler angle
+**     zetaa  zeta_A      equatorial precession: -1st 323 Euler angle
+**     thetaa theta_A     equatorial precession: 2nd 323 Euler angle
+**     pa     p_A         general precession
+**     gam    gamma_J2000 J2000.0 RA difference of ecliptic poles
+**     phi    phi_J2000   J2000.0 codeclination of ecliptic pole
+**     psi    psi_J2000   longitude difference of equator poles, J2000.0
+**
+**     The returned values are all radians.
+**
+**  3) Hilton et al. (2006) Table 1 also contains angles that depend on
+**     models distinct from the P03 precession theory itself, namely the
+**     IAU 2000A frame bias and nutation.  The quoted polynomials are
+**     used in other ERFA functions:
+**
+**     . eraXy06  contains the polynomial parts of the X and Y series.
+**
+**     . eraS06  contains the polynomial part of the s+XY/2 series.
+**
+**     . eraPfw06  implements the series for the Fukushima-Williams
+**       angles that are with respect to the GCRS pole (i.e. the variants
+**       that include frame bias).
+**
+**  4) The IAU resolution stipulated that the choice of parameterization
+**     was left to the user, and so an IAU compliant precession
+**     implementation can be constructed using various combinations of
+**     the angles returned by the present function.
+**
+**  5) The parameterization used by ERFA is the version of the Fukushima-
+**     Williams angles that refers directly to the GCRS pole.  These
+**     angles may be calculated by calling the function eraPfw06.  ERFA
+**     also supports the direct computation of the CIP GCRS X,Y by
+**     series, available by calling eraXy06.
+**
+**  6) The agreement between the different parameterizations is at the
+**     1 microarcsecond level in the present era.
+**
+**  7) When constructing a precession formulation that refers to the GCRS
+**     pole rather than the dynamical pole, it may (depending on the
+**     choice of angles) be necessary to introduce the frame bias
+**     explicitly.
+**
+**  8) It is permissible to re-use the same variable in the returned
+**     arguments.  The quantities are stored in the stated order.

+**
+**  This function forms three Euler angles which implement general
+**  precession from epoch J2000.0, using the IAU 2006 model.  Frame
+**  bias (the offset between ICRS and mean J2000.0) is included.
+**
+**  Given:
+**     date1,date2  double   TT as a 2-part Julian Date (Note 1)
+**
+**  Returned:
+**     bzeta        double   1st rotation: radians cw around z
+**     bz           double   3rd rotation: radians cw around z
+**     btheta       double   2nd rotation: radians ccw around y
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The traditional accumulated precession angles zeta_A, z_A,
+**     theta_A cannot be obtained in the usual way, namely through
+**     polynomial expressions, because of the frame bias.  The latter
+**     means that two of the angles undergo rapid changes near this
+**     date.  They are instead the results of decomposing the
+**     precession-bias matrix obtained by using the Fukushima-Williams
+**     method, which does not suffer from the problem.  The
+**     decomposition returns values which can be used in the
+**     conventional formulation and which include frame bias.
+**
+**  3) The three angles are returned in the conventional order, which
+**     is not the same as the order of the corresponding Euler
+**     rotations.  The precession-bias matrix is
+**     R_3(-z) x R_2(+theta) x R_3(-zeta).
+**
+**  4) Should zeta_A, z_A, theta_A angles be required that do not
+**     contain frame bias, they are available by calling the ERFA
+**     function eraP06e.

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) Naming the following points:
+**
+**           e = J2000.0 ecliptic pole,
+**           p = GCRS pole,
+**           E = mean ecliptic pole of date,
+**     and   P = mean pole of date,
+**
+**     the four Fukushima-Williams angles are as follows:
+**
+**        gamb = gamma_bar = epE
+**        phib = phi_bar = pE
+**        psib = psi_bar = pEP
+**        epsa = epsilon_A = EP
+**
+**  3) The matrix representing the combined effects of frame bias and
+**     precession is:
+**
+**        PxB = R_1(-epsa).R_3(-psib).R_1(phib).R_3(gamb)
+**
+**  4) The matrix representing the combined effects of frame bias,
+**     precession and nutation is simply:
+**
+**        NxPxB = R_1(-epsa-dE).R_3(-psib-dP).R_1(phib).R_3(gamb)
+**
+**     where dP and dE are the nutation components with respect to the
+**     ecliptic of date.

+**                                 +2 = warning: failed to converge
+**
+**  Notes:
+**
+**  1) The date date1+date2 is in the TDB time scale (in practice TT can
+**     be used) and is a Julian Date, apportioned in any convenient way
+**     between the two arguments.  For example, JD(TDB)=2450123.7 could
+**     be expressed in any of these ways, among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in cases
+**     where the loss of several decimal digits of resolution is
+**     acceptable.  The J2000 method is best matched to the way the
+**     argument is handled internally and will deliver the optimum
+**     resolution.  The MJD method and the date & time methods are both
+**     good compromises between resolution and convenience.  The limited
+**     accuracy of the present algorithm is such that any of the methods
+**     is satisfactory.
+**
+**  2) If an np value outside the range 1-8 is supplied, an error status
+**     (function value -1) is returned and the pv vector set to zeroes.
+**
+**  3) For np=3 the result is for the Earth-Moon Barycenter.  To obtain
+**     the heliocentric position and velocity of the Earth, use instead
+**     the ERFA function eraEpv00.
+**
+**  4) On successful return, the array pv contains the following:
+**
+**        pv[0][0]   x      }
+**        pv[0][1]   y      } heliocentric position, AU
+**        pv[0][2]   z      }
+**
+**        pv[1][0]   xdot   }
+**        pv[1][1]   ydot   } heliocentric velocity, AU/d
+**        pv[1][2]   zdot   }
+**
+**     The reference frame is equatorial and is with respect to the
+**     mean equator and equinox of epoch J2000.0.
+**
+**  5) The algorithm is due to J.L. Simon, P. Bretagnon, J. Chapront,
+**     M. Chapront-Touze, G. Francou and J. Laskar (Bureau des
+**     Longitudes, Paris, France).  From comparisons with JPL
+**     ephemeris DE102, they quote the following maximum errors
+**     over the interval 1800-2050:
+**
+**                     L (arcsec)    B (arcsec)      R (km)
+**
+**        Mercury          4             1             300
+**        Venus            5             1             800
+**        EMB              6             1            1000
+**        Mars            17             1            7700
+**        Jupiter         71             5           76000
+**        Saturn          81            13          267000
+**        Uranus          86             7          712000
+**        Neptune         11             1          253000
+**
+**     Over the interval 1000-3000, they report that the accuracy is no
+**     worse than 1.5 times that over 1800-2050.  Outside 1000-3000 the
+**     accuracy declines.
+**
+**     Comparisons of the present function with the JPL DE200 ephemeris
+**     give the following RMS errors over the interval 1960-2025:
+**
+**                      position (km)     velocity (m/s)
+**
+**        Mercury            334               0.437
+**        Venus             1060               0.855
+**        EMB               2010               0.815
+**        Mars              7690               1.98
+**        Jupiter          71700               7.70
+**        Saturn          199000              19.4
+**        Uranus          564000              16.4
+**        Neptune         158000              14.4
+**
+**     Comparisons against DE200 over the interval 1800-2100 gave the
+**     following maximum absolute differences.  (The results using
+**     DE406 were essentially the same.)
+**
+**                   L (arcsec)   B (arcsec)     R (km)   Rdot (m/s)
+**
+**        Mercury        7            1            500       0.7
+**        Venus          7            1           1100       0.9
+**        EMB            9            1           1300       1.0
+**        Mars          26            1           9000       2.5
+**        Jupiter       78            6          82000       8.2
+**        Saturn        87           14         263000      24.6
+**        Uranus        86            7         661000      27.4
+**        Neptune       11            2         248000      21.4
+**
+**  6) The present ERFA re-implementation of the original Simon et al.
+**     Fortran code differs from the original in the following respects:
+**
+**       *  C instead of Fortran.
+**
+**       *  The date is supplied in two parts.
+**
+**       *  The result is returned only in equatorial Cartesian form;
+**          the ecliptic longitude, latitude and radius vector are not
+**          returned.
+**
+**       *  The result is in the J2000.0 equatorial frame, not ecliptic.
+**
+**       *  More is done in-line: there are fewer calls to subroutines.
+**
+**       *  Different error/warning status values are used.
+**
+**       *  A different Kepler's-equation-solver is used (avoiding
+**          use of double precision complex).
+**
+**       *  Polynomials in t are nested to minimize rounding errors.
+**
+**       *  Explicit double constants are used to avoid mixed-mode
+**          expressions.
+**
+**     None of the above changes affects the result significantly.
+**
+**  7) The returned status indicates the most serious condition
+**     encountered during execution of the function.  Illegal np is
+**     considered the most serious, overriding failure to converge,
+**     which in turn takes precedence over the remote date warning.

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)

+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The caller is responsible for providing the nutation components;
+**     they are in longitude and obliquity, in radians and are with
+**     respect to the equinox and ecliptic of date.  For high-accuracy
+**     applications, free core nutation should be included as well as
+**     any other relevant corrections to the position of the CIP.
+**
+**  3) The returned mean obliquity is consistent with the IAU 2000
+**     precession-nutation models.
+**
+**  4) The matrix rb transforms vectors from GCRS to J2000.0 mean
+**     equator and equinox by applying frame bias.
+**
+**  5) The matrix rp transforms vectors from J2000.0 mean equator and
+**     equinox to mean equator and equinox of date by applying
+**     precession.
+**
+**  6) The matrix rbp transforms vectors from GCRS to mean equator and
+**     equinox of date by applying frame bias then precession.  It is
+**     the product rp x rb.
+**
+**  7) The matrix rn transforms vectors from mean equator and equinox of
+**     date to true equator and equinox of date by applying the nutation
+**     (luni-solar + planetary).
+**
+**  8) The matrix rbpn transforms vectors from GCRS to true equator and
+**     equinox of date.  It is the product rn x rbp, applying frame
+**     bias, precession and nutation in that order.
+**
+**  9) It is permissible to re-use the same array in the returned
+**     arguments.  The arrays are filled in the order given.

+**
+**  Notes:
+**
+**  1)  The TT date date1+date2 is a Julian Date, apportioned in any
+**      convenient way between the two arguments.  For example,
+**      JD(TT)=2450123.7 could be expressed in any of these ways,
+**      among others:
+**
+**             date1          date2
+**
+**          2450123.7           0.0       (JD method)
+**          2451545.0       -1421.3       (J2000 method)
+**          2400000.5       50123.2       (MJD method)
+**          2450123.5           0.2       (date & time method)
+**
+**      The JD method is the most natural and convenient to use in
+**      cases where the loss of several decimal digits of resolution
+**      is acceptable.  The J2000 method is best matched to the way
+**      the argument is handled internally and will deliver the
+**      optimum resolution.  The MJD method and the date & time methods
+**      are both good compromises between resolution and convenience.
+**
+**  2)  The nutation components (luni-solar + planetary, IAU 2000B) in
+**      longitude and obliquity are in radians and with respect to the
+**      equinox and ecliptic of date.  For more accurate results, but
+**      at the cost of increased computation, use the eraPn00a function.
+**      For the utmost accuracy, use the eraPn00  function, where the
+**      nutation components are caller-specified.
+**
+**  3)  The mean obliquity is consistent with the IAU 2000 precession.
+**
+**  4)  The matrix rb transforms vectors from GCRS to J2000.0 mean
+**      equator and equinox by applying frame bias.
+**
+**  5)  The matrix rp transforms vectors from J2000.0 mean equator and
+**      equinox to mean equator and equinox of date by applying
+**      precession.
+**
+**  6)  The matrix rbp transforms vectors from GCRS to mean equator and
+**      equinox of date by applying frame bias then precession.  It is
+**      the product rp x rb.
+**
+**  7)  The matrix rn transforms vectors from mean equator and equinox
+**      of date to true equator and equinox of date by applying the
+**      nutation (luni-solar + planetary).
+**
+**  8)  The matrix rbpn transforms vectors from GCRS to true equator and
+**      equinox of date.  It is the product rn x rbp, applying frame
+**      bias, precession and nutation in that order.
+**
+**  9)  The X,Y,Z coordinates of the IAU 2000B Celestial Intermediate
+**      Pole are elements (3,1-3) of the matrix rbpn.
+**
+**  10) It is permissible to re-use the same array in the returned
+**      arguments.  The arrays are filled in the stated order.

+**      The JD method is the most natural and convenient to use in

+**      optimum resolution.  The MJD method and the date & time methods
+**      are both good compromises between resolution and convenience.
+**
+**  2)  The nutation components (luni-solar + planetary, IAU 2000A) in
+**      longitude and obliquity are in radians and with respect to the
+**      equinox and ecliptic of date.  Free core nutation is omitted;
+**      for the utmost accuracy, use the eraPn06 function, where the
+**      nutation components are caller-specified.
+**
+**  3)  The mean obliquity is consistent with the IAU 2006 precession.
+**
+**  4)  The matrix rb transforms vectors from GCRS to mean J2000.0 by
+**      applying frame bias.
+**
+**  5)  The matrix rp transforms vectors from mean J2000.0 to mean of
+**      date by applying precession.
+**
+**  6)  The matrix rbp transforms vectors from GCRS to mean of date by
+**      applying frame bias then precession.  It is the product rp x rb.
+**
+**  7)  The matrix rn transforms vectors from mean of date to true of
+**      date by applying the nutation (luni-solar + planetary).
+**
+**  8)  The matrix rbpn transforms vectors from GCRS to true of date
+**      (CIP/equinox).  It is the product rn x rbp, applying frame bias,
+**      precession and nutation in that order.
+**
+**  9)  The X,Y,Z coordinates of the IAU 2006/2000A Celestial
+**      Intermediate Pole are elements (1,1-3) of the matrix rbpn.

+**
+**  Notes:
+**
+**  1) The TDB date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TDB)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The matrix operates in the sense V(date) = rmatpn * V(J2000),
+**     where the p-vector V(date) is with respect to the true equatorial
+**     triad of date date1+date2 and the p-vector V(J2000) is with
+**     respect to the mean equatorial triad of epoch J2000.0.

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The precession adjustments are expressed as "nutation
+**     components", corrections in longitude and obliquity with respect
+**     to the J2000.0 equinox and ecliptic.
+**
+**  3) Although the precession adjustments are stated to be with respect
+**     to Lieske et al. (1977), the MHB2000 model does not specify which
+**     set of Euler angles are to be used and how the adjustments are to
+**     be applied.  The most literal and straightforward procedure is to
+**     adopt the 4-rotation epsilon_0, psi_A, omega_A, xi_A option, and
+**     to add dpsipr to psi_A and depspr to both omega_A and eps_A.
+**
+**  4) This is an implementation of one aspect of the IAU 2000A nutation
+**     model, formally adopted by the IAU General Assembly in 2000,
+**     namely MHB2000 (Mathews et al. 2002).

+**  IAU 1976 precession model.
+**
+**  This function forms the three Euler angles which implement general
+**  precession between two epochs, using the IAU 1976 model (as for
+**  the FK5 catalog).
+**
+**  Given:
+**     ep01,ep02   double    TDB starting epoch (Note 1)
+**     ep11,ep12   double    TDB ending epoch (Note 1)
+**
+**  Returned:
+**     zeta        double    1st rotation: radians cw around z
+**     z           double    3rd rotation: radians cw around z
+**     theta       double    2nd rotation: radians ccw around y
+**
+**  Notes:
+**
+**  1) The epochs ep01+ep02 and ep11+ep12 are Julian Dates, apportioned
+**     in any convenient way between the arguments epn1 and epn2.  For
+**     example, JD(TDB)=2450123.7 could be expressed in any of these
+**     ways, among others:
+**
+**             epn1          epn2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in cases
+**     where the loss of several decimal digits of resolution is
+**     acceptable.  The J2000 method is best matched to the way the
+**     argument is handled internally and will deliver the optimum
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**     The two epochs may be expressed using different methods, but at
+**     the risk of losing some resolution.
+**
+**  2) The accumulated precession angles zeta, z, theta are expressed
+**     through canonical polynomials which are valid only for a limited
+**     time span.  In addition, the IAU 1976 precession rate is known to
+**     be imperfect.  The absolute accuracy of the present formulation
+**     is better than 0.1 arcsec from 1960AD to 2040AD, better than
+**     1 arcsec from 1640AD to 2360AD, and remains below 3 arcsec for
+**     the whole of the period 500BC to 3000AD.  The errors exceed
+**     10 arcsec outside the range 1200BC to 3900AD, exceed 100 arcsec
+**     outside 4200BC to 5600AD and exceed 1000 arcsec outside 6800BC to
+**     8200AD.
+**
+**  3) The three angles are returned in the conventional order, which
+**     is not the same as the order of the corresponding Euler
+**     rotations.  The precession matrix is
+**     R_3(-z) x R_2(+theta) x R_3(-zeta).

+**                             -2 = null position vector
+**
+**  Notes:
+**
+**  1) The specified pv-vector is the coordinate direction (and its rate
+**     of change) for the date at which the light leaving the star
+**     reached the solar-system barycenter.
+**
+**  2) The star data returned by this function are "observables" for an
+**     imaginary observer at the solar-system barycenter.  Proper motion
+**     and radial velocity are, strictly, in terms of barycentric
+**     coordinate time, TCB.  For most practical applications, it is
+**     permissible to neglect the distinction between TCB and ordinary
+**     "proper" time on Earth (TT/TAI).  The result will, as a rule, be
+**     limited by the intrinsic accuracy of the proper-motion and
+**     radial-velocity data;  moreover, the supplied pv-vector is likely
+**     to be merely an intermediate result (for example generated by the
+**     function eraStarpv), so that a change of time unit will cancel
+**     out overall.
+**
+**     In accordance with normal star-catalog conventions, the object's
+**     right ascension and declination are freed from the effects of
+**     secular aberration.  The frame, which is aligned to the catalog
+**     equator and equinox, is Lorentzian and centered on the SSB.
+**
+**     Summarizing, the specified pv-vector is for most stars almost
+**     identical to the result of applying the standard geometrical
+**     "space motion" transformation to the catalog data.  The
+**     differences, which are the subject of the Stumpff paper cited
+**     below, are:
+**
+**     (i) In stars with significant radial velocity and proper motion,
+**     the constantly changing light-time distorts the apparent proper
+**     motion.  Note that this is a classical, not a relativistic,
+**     effect.
+**
+**     (ii) The transformation complies with special relativity.
+**
+**  3) Care is needed with units.  The star coordinates are in radians
+**     and the proper motions in radians per Julian year, but the
+**     parallax is in arcseconds; the radial velocity is in km/s, but
+**     the pv-vector result is in AU and AU/day.
+**
+**  4) The proper motions are the rate of change of the right ascension
+**     and declination at the catalog epoch and are in radians per Julian
+**     year.  The RA proper motion is in terms of coordinate angle, not
+**     true angle, and will thus be numerically larger at high
+**     declinations.
+**
+**  5) Straight-line motion at constant speed in the inertial frame is
+**     assumed.  If the speed is greater than or equal to the speed of
+**     light, the function aborts with an error status.
+**
+**  6) The inverse transformation is performed by the function eraStarpv.

+**
+**  The CIO locator s, positioning the Celestial Intermediate Origin on
+**  the equator of the Celestial Intermediate Pole, given the CIP's X,Y
+**  coordinates.  Compatible with IAU 2000A precession-nutation.
+**
+**  Given:
+**     date1,date2   double    TT as a 2-part Julian Date (Note 1)
+**     x,y           double    CIP coordinates (Note 3)
+**
+**  Returned (function value):
+**                   double    the CIO locator s in radians (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The CIO locator s is the difference between the right ascensions
+**     of the same point in two systems:  the two systems are the GCRS
+**     and the CIP,CIO, and the point is the ascending node of the
+**     CIP equator.  The quantity s remains below 0.1 arcsecond
+**     throughout 1900-2100.
+**
+**  3) The series used to compute s is in fact for s+XY/2, where X and Y
+**     are the x and y components of the CIP unit vector;  this series
+**     is more compact than a direct series for s would be.  This
+**     function requires X,Y to be supplied by the caller, who is
+**     responsible for providing values that are consistent with the
+**     supplied date.
+**
+**  4) The model is consistent with the IAU 2000A precession-nutation.

+**     eraFal03     mean anomaly of the Moon

+**
+**  The CIO locator s, positioning the Celestial Intermediate Origin on
+**  the equator of the Celestial Intermediate Pole, using the IAU 2000A
+**  precession-nutation model.
+**
+**  Given:
+**     date1,date2  double    TT as a 2-part Julian Date (Note 1)
+**
+**  Returned (function value):
+**                  double    the CIO locator s in radians (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The CIO locator s is the difference between the right ascensions
+**     of the same point in two systems.  The two systems are the GCRS
+**     and the CIP,CIO, and the point is the ascending node of the
+**     CIP equator.  The CIO locator s remains a small fraction of
+**     1 arcsecond throughout 1900-2100.
+**
+**  3) The series used to compute s is in fact for s+XY/2, where X and Y
+**     are the x and y components of the CIP unit vector;  this series
+**     is more compact than a direct series for s would be.  The present
+**     function uses the full IAU 2000A nutation model when predicting
+**     the CIP position.  Faster results, with no significant loss of
+**     accuracy, can be obtained via the function eraS00b, which uses
+**     instead the IAU 2000B truncated model.

+**
+**  The CIO locator s, positioning the Celestial Intermediate Origin on
+**  the equator of the Celestial Intermediate Pole, given the CIP's X,Y
+**  coordinates.  Compatible with IAU 2006/2000A precession-nutation.
+**
+**  Given:
+**     date1,date2   double    TT as a 2-part Julian Date (Note 1)
+**     x,y           double    CIP coordinates (Note 3)
+**
+**  Returned (function value):
+**                   double    the CIO locator s in radians (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The CIO locator s is the difference between the right ascensions
+**     of the same point in two systems:  the two systems are the GCRS
+**     and the CIP,CIO, and the point is the ascending node of the
+**     CIP equator.  The quantity s remains below 0.1 arcsecond
+**     throughout 1900-2100.
+**
+**  3) The series used to compute s is in fact for s+XY/2, where X and Y
+**     are the x and y components of the CIP unit vector;  this series
+**     is more compact than a direct series for s would be.  This
+**     function requires X,Y to be supplied by the caller, who is
+**     responsible for providing values that are consistent with the
+**     supplied date.
+**
+**  4) The model is consistent with the "P03" precession (Capitaine et
+**     al. 2003), adopted by IAU 2006 Resolution 1, 2006, and the
+**     IAU 2000A nutation (with P03 adjustments).

+**
+**  The CIO locator s, positioning the Celestial Intermediate Origin on
+**  the equator of the Celestial Intermediate Pole, using the IAU 2006
+**  precession and IAU 2000A nutation models.
+**
+**  Given:
+**     date1,date2  double    TT as a 2-part Julian Date (Note 1)
+**
+**  Returned (function value):
+**                  double    the CIO locator s in radians (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The CIO locator s is the difference between the right ascensions
+**     of the same point in two systems.  The two systems are the GCRS
+**     and the CIP,CIO, and the point is the ascending node of the
+**     CIP equator.  The CIO locator s remains a small fraction of
+**     1 arcsecond throughout 1900-2100.
+**
+**  3) The series used to compute s is in fact for s+XY/2, where X and Y
+**     are the x and y components of the CIP unit vector;  this series is
+**     more compact than a direct series for s would be.  The present
+**     function uses the full IAU 2000A nutation model when predicting
+**     the CIP position.

+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)

+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The TIO locator s' is obtained from polar motion observations by
+**     numerical integration, and so is in essence unpredictable.
+**     However, it is dominated by a secular drift of about
+**     47 microarcseconds per century, which is the approximation
+**     evaluated by the present function.

+**
+**  Notes:
+**
+**  1) The starting and ending TDB dates ep1a+ep1b and ep2a+ep2b are
+**     Julian Dates, apportioned in any convenient way between the two
+**     parts (A and B).  For example, JD(TDB)=2450123.7 could be
+**     expressed in any of these ways, among others:
+**
+**             epna          epnb
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) In accordance with normal star-catalog conventions, the object's
+**     right ascension and declination are freed from the effects of
+**     secular aberration.  The frame, which is aligned to the catalog
+**     equator and equinox, is Lorentzian and centered on the SSB.
+**
+**     The proper motions are the rate of change of the right ascension
+**     and declination at the catalog epoch and are in radians per TDB
+**     Julian year.
+**
+**     The parallax and radial velocity are in the same frame.
+**
+**  3) Care is needed with units.  The star coordinates are in radians
+**     and the proper motions in radians per Julian year, but the
+**     parallax is in arcseconds.
+**
+**  4) The RA proper motion is in terms of coordinate angle, not true
+**     angle.  If the catalog uses arcseconds for both RA and Dec proper
+**     motions, the RA proper motion will need to be divided by cos(Dec)
+**     before use.
+**
+**  5) Straight-line motion at constant speed, in the inertial frame,
+**     is assumed.
+**
+**  6) An extremely small (or zero or negative) parallax is interpreted
+**     to mean that the object is on the "celestial sphere", the radius
+**     of which is an arbitrary (large) value (see the eraStarpv
+**     function for the value used).  When the distance is overridden in
+**     this way, the status, initially zero, has 1 added to it.
+**
+**  7) If the space velocity is a significant fraction of c (see the
+**     constant VMAX in the function eraStarpv),  it is arbitrarily set
+**     to zero.  When this action occurs, 2 is added to the status.
+**
+**  8) The relativistic adjustment carried out in the eraStarpv function
+**     involves an iterative calculation.  If the process fails to
+**     converge within a set number of iterations, 4 is added to the
+**     status.

+**
+**  Notes:
+**
+**  1) The star data accepted by this function are "observables" for an
+**     imaginary observer at the solar-system barycenter.  Proper motion
+**     and radial velocity are, strictly, in terms of barycentric
+**     coordinate time, TCB.  For most practical applications, it is
+**     permissible to neglect the distinction between TCB and ordinary
+**     "proper" time on Earth (TT/TAI).  The result will, as a rule, be
+**     limited by the intrinsic accuracy of the proper-motion and
+**     radial-velocity data;  moreover, the pv-vector is likely to be
+**     merely an intermediate result, so that a change of time unit
+**     would cancel out overall.
+**
+**     In accordance with normal star-catalog conventions, the object's
+**     right ascension and declination are freed from the effects of
+**     secular aberration.  The frame, which is aligned to the catalog
+**     equator and equinox, is Lorentzian and centered on the SSB.
+**
+**  2) The resulting position and velocity pv-vector is with respect to
+**     the same frame and, like the catalog coordinates, is freed from
+**     the effects of secular aberration.  Should the "coordinate
+**     direction", where the object was located at the catalog epoch, be
+**     required, it may be obtained by calculating the magnitude of the
+**     position vector pv[0][0-2] dividing by the speed of light in
+**     AU/day to give the light-time, and then multiplying the space
+**     velocity pv[1][0-2] by this light-time and adding the result to
+**     pv[0][0-2].
+**
+**     Summarizing, the pv-vector returned is for most stars almost
+**     identical to the result of applying the standard geometrical
+**     "space motion" transformation.  The differences, which are the
+**     subject of the Stumpff paper referenced below, are:
+**
+**     (i) In stars with significant radial velocity and proper motion,
+**     the constantly changing light-time distorts the apparent proper
+**     motion.  Note that this is a classical, not a relativistic,
+**     effect.
+**
+**     (ii) The transformation complies with special relativity.
+**
+**  3) Care is needed with units.  The star coordinates are in radians
+**     and the proper motions in radians per Julian year, but the
+**     parallax is in arcseconds; the radial velocity is in km/s, but
+**     the pv-vector result is in AU and AU/day.
+**
+**  4) The RA proper motion is in terms of coordinate angle, not true
+**     angle.  If the catalog uses arcseconds for both RA and Dec proper
+**     motions, the RA proper motion will need to be divided by cos(Dec)
+**     before use.
+**
+**  5) Straight-line motion at constant speed, in the inertial frame,
+**     is assumed.
+**
+**  6) An extremely small (or zero or negative) parallax is interpreted
+**     to mean that the object is on the "celestial sphere", the radius
+**     of which is an arbitrary (large) value (see the constant PXMIN).
+**     When the distance is overridden in this way, the status,
+**     initially zero, has 1 added to it.
+**
+**  7) If the space velocity is a significant fraction of c (see the
+**     constant VMAX), it is arbitrarily set to zero.  When this action
+**     occurs, 2 is added to the status.
+**
+**  8) The relativistic adjustment involves an iterative calculation.
+**     If the process fails to converge within a set number (IMAX) of
+**     iterations, 4 is added to the status.
+**
+**  9) The inverse transformation is performed by the function
+**     eraPvstar.

+**     eraS2pv      spherical coordinates to pv-vector
+**     eraPm        modulus of p-vector

+**     compensates for the drift between TCB and terrestrial time TT,

+**     relationship between TT and TCB depends on the adopted solar
+**     system ephemeris, the degree of alignment between TDB and TT over
+**     long intervals will vary according to which ephemeris is used.
+**     Former definitions of TDB attempted to avoid this problem by
+**     stipulating that TDB and TT should differ only by periodic
+**     effects.  This is a good description of the nature of the
+**     relationship but eluded precise mathematical formulation.  The
+**     conventional linear relationship adopted in 2006 sidestepped
+**     these difficulties whilst delivering a TDB that in practice was
+**     consistent with values before that date.
+**
+**  3) TDB is essentially the same as Teph, the time argument for the
+**     JPL solar system ephemerides.

+**
+**  2) The 2006 IAU General Assembly introduced a conventional linear
+**     transformation between TDB and TCB.  This transformation
+**     compensates for the drift between TCB and terrestrial time TT,
+**     and keeps TDB approximately centered on TT.  Because the
+**     relationship between TT and TCB depends on the adopted solar
+**     system ephemeris, the degree of alignment between TDB and TT over
+**     long intervals will vary according to which ephemeris is used.
+**     Former definitions of TDB attempted to avoid this problem by
+**     stipulating that TDB and TT should differ only by periodic
+**     effects.  This is a good description of the nature of the
+**     relationship but eluded precise mathematical formulation.  The
+**     conventional linear relationship adopted in 2006 sidestepped
+**     these difficulties whilst delivering a TDB that in practice was
+**     consistent with values before that date.
+**
+**  3) TDB is essentially the same as Teph, the time argument for the
+**     JPL solar system ephemerides.

+**  Time scale transformation:  Universal Time, UT1, to Coordinated
+**  Universal Time, UTC.
+**
+**  Given:
+**     ut11,ut12  double   UT1 as a 2-part Julian Date (Note 1)
+**     dut1       double   Delta UT1: UT1-UTC in seconds (Note 2)
+**
+**  Returned:
+**     utc1,utc2  double   UTC as a 2-part quasi Julian Date (Notes 3,4)
+**
+**  Returned (function value):
+**                int      status: +1 = dubious year (Note 5)
+**                                  0 = OK
+**                                 -1 = unacceptable date
+**
+**  Notes:
+**
+**  1) ut11+ut12 is Julian Date, apportioned in any convenient way
+**     between the two arguments, for example where ut11 is the Julian
+**     Day Number and ut12 is the fraction of a day.  The returned utc1
+**     and utc2 form an analogous pair, except that a special convention
+**     is used, to deal with the problem of leap seconds - see Note 3.
+**
+**  2) Delta UT1 can be obtained from tabulations provided by the
+**     International Earth Rotation and Reference Systems Service.  The
+**     value changes abruptly by 1s at a leap second;  however, close to
+**     a leap second the algorithm used here is tolerant of the "wrong"
+**     choice of value being made.
+**
+**  3) JD cannot unambiguously represent UTC during a leap second unless
+**     special measures are taken.  The convention in the present
+**     function is that the returned quasi JD day UTC1+UTC2 represents
+**     UTC days whether the length is 86399, 86400 or 86401 SI seconds.
+**
+**  4) The function eraD2dtf can be used to transform the UTC quasi-JD
+**     into calendar date and clock time, including UTC leap second
+**     handling.
+**
+**  5) The warning status "dubious year" flags UTCs that predate the
+**     introduction of the time scale and that are too far in the future
+**     to be trusted.  See eraDat for further details.

+**
+**  X,Y coordinates of celestial intermediate pole from series based
+**  on IAU 2006 precession and IAU 2000A nutation.
+**
+**  Given:
+**     date1,date2  double     TT as a 2-part Julian Date (Note 1)
+**
+**  Returned:
+**     x,y          double     CIP X,Y coordinates (Note 2)
+**
+**  Notes:
+**
+**  1) The TT date date1+date2 is a Julian Date, apportioned in any
+**     convenient way between the two arguments.  For example,
+**     JD(TT)=2450123.7 could be expressed in any of these ways,
+**     among others:
+**
+**            date1          date2
+**
+**         2450123.7           0.0       (JD method)
+**         2451545.0       -1421.3       (J2000 method)
+**         2400000.5       50123.2       (MJD method)
+**         2450123.5           0.2       (date & time method)
+**
+**     The JD method is the most natural and convenient to use in
+**     cases where the loss of several decimal digits of resolution
+**     is acceptable.  The J2000 method is best matched to the way
+**     the argument is handled internally and will deliver the
+**     optimum resolution.  The MJD method and the date & time methods
+**     are both good compromises between resolution and convenience.
+**
+**  2) The X,Y coordinates are those of the unit vector towards the
+**     celestial intermediate pole.  They represent the combined effects
+**     of frame bias, precession and nutation.
+**
+**  3) The fundamental arguments used are as adopted in IERS Conventions
+**     (2003) and are from Simon et al. (1994) and Souchay et al.
+**     (1999).
+**
+**  4) This is an alternative to the angles-based method, via the ERFA
+**     function eraFw2xy and as used in eraXys06a for example.  The two
+**     methods agree at the 1 microarcsecond level (at present), a
+**     negligible amount compared with the intrinsic accuracy of the
+**     models.  However, it would be unwise to mix the two methods
+**     (angles-based and series-based) in a single application.

+**  Although the intent is to replicate the SOFA API (other than
+**  replacement of prefix names) and results (with the exception of
+**  bugs;  any that are discovered will be fixed), SOFA is not
+**  responsible for any errors found in this version of the library.
