Description:
The observations of the faint satellites of Jupiter J6, J7, J8 and J9
have been collected. Numerical integrations have been performed and
fitted to ancient and modern observations. Ephemerides of the
equatorial jovicentric rectangular coordinates of the satellites are
presented under the form of Poisson series, covering 150 years from
1900. Numerical tools (tables and softwares) are provided to the users
for a practical reconstruction of the ephemerides.

Explanations:
The program satxjup.f computes the geocentric positions of Jupiter
satellites J6, J7, J8, J9 for 10 values of the time (dynamical time)
with 5400 days step.
Starting Julian date = 2415020.5 (1900/Jan./10h).
The resulting values appear on the screen : geocentric rectangular
positions X, Y, Z (AU) of the satellites (equinox and equator J2000)
