Ephemerides of planets between 1900 and 2100 (1998 update)

ADC_Keywords: Ephemerides ; Planets
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.

Contents:
The presentation of the series is given in file series96.doc. 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.
