Self-contained ephemeris calculator
C program computes ephemerides of Sun, Moon, planets, comets, and stars using rigorous reduction methods from the _Astronomical Almanac_ and related sources. Includes PLAN404 series (see below) for positions of the planets, and a long-term extension of modern Lunar theory for the Moon's position. Reads ASCII file catalogues of stars and orbital elements. Displays all adjustments as it finds local azimuth and elevation, rise and set times, etc. Windows or MSDOS (Microsoft and Borland), Unix, VAX make files. Archive includes MSDOS executable program.
