SOME GENERAL INFORMATION ABOUT THIS VSOP87 VENUS EPHEMERIS DEMO The purpose of this program is to compute an apparent geocentric equatorial Venus ephemeris for any Gregorian calendar date within the ephemeris span from 1583 to 5999 AD based on the VSOP87 theory. ------- CAVEAT: Be cautious when entering the year/month values. This program is only a simplified demo and does NOT do extensive error checking for invalid arguments. Valid input arguments should return valid results. Whenever possible, compare against known check values or against another source of similar VSOP87C computations for consistency. ---------------- TIME SCALE USED: The program uses the system clock for the time (UTC). However, the actual time scale used is the TT scale. Without any Delta T adjustment, UTC is being treated as equivalent to TT. --------------------------------------------------------------------------- SOURCE CODE: There is a link below to the complete PHP source code for this program.
