This directory contains a modified version of Stephen L. Moshier's Astronomical Almanac package V5.1. Many changes were made to make the code compile under gcc 2.3.3 in ANSI mode on a Sun IPC (4/40) running SUNOS 4.1.2 (SOLARIS 1.1.2), and using gmake 3.63. There were also many modifications made to the code in order to make the interface to the UNIX satellite tracking software easier. The source code was placed under the Revision Control System (RCS) in order to track modifications to the code and as a safety feature while modifying the code. Directions for using the almanac program are contained in the README.orig file. Note that the local site information must be contained in either a ~/.site.ini file or a ./.site.ini file. The almanac program has been checked against an example run furnished with the original software as well as with the Astronomical Almanac for the years 1981, 1986, and 1993.
