aa200c

AA200 reads astronomical ephemerides, in the data format produced by Jet Propulsion Laboratory, and reduces the barycentric coordinates to printouts of geocentric and topocentric place. Specific configurations for the DE406 CD-ROM from Willmann-Bell, DE406, DE405, DE404, DE403, DE400, DE245, DE200, DE102, and DE118I.ZIP ephemerides are supplied. The ephemeris data files themselves are not supplied; get them from Willmann-Bell or from JPL's ftp site. Answers for DE200 from this program should agree with Astronomical Almanac tabulations from about 1984 onward. Additionally, the program can reduce star catalogue positions given in either the FK4 or FK5 system. It can also find positions from heliocentric orbital elements. Source code listings in C language are supplied with MSDOS (Microsoft and Borland compilers) and Unix make files. The archive includes an MSDOS executable program configured for the new Willmann-Bell CD ROM. Latest update 4/17/00. Previous version aa200b.zip
