CONTENTS :

    Planetary Ephemerides (1900-2100) version 96.

    Planetary motions have been represented with series resulting of an
    approximation by frequency analysis of JPL numerical integration DE403.

    Series allow to compute the most usual planetary ephemerides between 1900
    and 2100 for the 9 main planets and Sun.

DESCRIPTION :

    An executable DOS program, planeph.exe, is provided for computing the 
    planetary ephemerides between 1900 and 2100 :
    - Geometric coordinates.
    - Apparent coordinates.
    - Astrometric coordinates.
    - Topocentric coordinates.
    - Physical ephemeris.
    - Osculating elements.
    - Rising, Setting, Transits times.
    - Sidereal Time, Obiquity, Nutation.
    - Calendar. 

    This program runs under DOS 6.2 operating system and following versions
    and needs an arithmetic processor.

    The file planeph.doc gives explanations for using this program with the
    data sets :
    - planeph.tab (planetary tables),
    - planeph.loc (locations coordinates).
