libAstronomy provides a set of astronomical routines to ease the calculation of ephemerides. It includes mathematical functions to compensate various astronomical phenomena like precession, nutation, etc. The getconstellation routine finds the constellation for a given coordinate. It also calculates the positions of the sun and moon in two different precise ways.

Release Notes: A fix for a bug in data files, routines for all planets, uniting of lower-precision routines in module 'fast.c', and some sample files to show how to implement the new routines.
Release Notes: Two fast routines for the precise calculation of sun and moon positions were added, as well as some basic functions and three sample programs. The documentation has been somewhat redesigned, but needs more work.
