DESCRIPTION:

The SSO Planetary-Satellite Data File contains all information needed to compute
the heliocentric J2000 position of a selected set of planetary satellites. This
file is prepared offline by the SSO Prediction Cognizant Engineer, David Tholen,
and updated versions are provided to WSDC on a  schedule coordinated with
observation opportunities. The file contains ASCII text data arranged in columns
of fixed width. The first line contains text labels, and all subsequent lines
contain satellite information, one satellite per line.

Notes:
1.) Units are au^3/day^2
2.) State vector arrays consist of six elements, the three components of the
    position vector in units of AU and the three components of the velocity
    vector in AU/day; all vectors are planetocentric.
