Calcul de la position des planètes . Le programme SERIES est traduit en PASCAL . Les fichiers originaux des séries ont été modifiés afin de permettre leur accès en PASCAL : - Un zéro est ajouté après le point décimal. - Un espace est ajouté pour séparer deux champs contigus. - Pour les distinguer ces fichiers sont renommés SERIE96P.xxx Description originale du catalogue : VI/87 Planetary Ephemerides (Chapront+ 1996) ================================================================================ Ephemerides of planets between 1900 and 2100 Chapront J., Francou G. ================================================================================ ADC_Keywords: Ephemerides Keywords: planets - ephemerides - celestial mechanics Description: 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. Authors' Address: J. Chapront, G.

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.f is provided to illustrate the use of the series in the case of the computation of astrometric coordinates. An executable DOS program, planeph.exe, allows to compute the most usual planetary ephemerides with the series between 1900 to 2100. The file planeph.doc gives explanations for using this program with the data sets planeph.tab and planeph.loc.
