This is a suite of vector/matrix routines and various utilities that
underpin the astronomy algorithms, which include routines for the
following:
* Calendars
* Time Scales
* Earth rotation and sidereal time
* Ephemerides (medium precision)
* Geocentric/geodetic transformations
* Precession, nutation, polar motion
* Star space motion
* Star catalogue conversion
This is the ANSI C version of the library.
The International Astronomical Union's SOFA service has the task of
establishing and maintaining an accessible and authoritative set of
algorithms and procedures that implement standard models used in
fundamental astronomy.
