Abstract:

Three computer programs were written to provide a means of using the available ephemeris data in numerical studies of the motions of celestial bodies. These programs are written in Fortran 63 language for use on the Control Data Corporation 1604. The main program PHEMERIS is an interpolation subroutine which provides the user with rectangular coordinates and rectangular components of the velocity of any one or all of the major bodies of the solar system. The information may be obtained in a coordinate system referenced to mean equinox and equator of 1950 or to the equinox and ecliptic of 1950. The reference frame may be centered in the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, Moon, or at the Earth-Moon Barycenter. The nutation and nutation rate in longitude and obliquity are made available. The information may be obtained for any time point between 30 December 1949 and 5 January 2000 with an accuracy of 12 figures. Author
