Chapront, G. Francou CONTENTS : Planetary series (1900-2100) version 96. Planetary motions have been represented with series resulting of an approximation by frequency analysis of JPL numerical integration DE403. Series represent the heliocentric coordinates of planets as functions of time between 1900 and 2100 for the 9 bodies : Mercury, Venus, Earth-Moon Barycenter, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The method allows to compute planetary ephemerides with the aid of compact tables and keeps accuracy of published ephemerides.

The planetary series are in files series96.xxx (one file per planet). A Fortran subroutine series96.sub (96.12) uses the series for computing the heliocentric rectangular coordinates of planets. A Fortran program series96.for is provided to illustrate the use of the series in the case of the computation of astrometric coordinates.
