%description
Calculate and plot the configuration of Jupiter's four largest satellites
(known as Galilean satellites) for a given date and time (ET - Ephemeris
Time). The 'galsat' function returns numerical values of the satellites’
positions. x – the apparent rectangular coordinate of the satellite with
respect to the center of Jupiter’s disk in the equatorial plane in the
units of Jupiter’s equatorial radius; X is positive toward the west, y –
the apparent rectangular coordinate of the satellite with respect to the
center of Jupiter’s disk from the equatorial plane in the units of
Jupiter’s equatorial radius; Y is positive toward the north. For more
details see Meeus (1988, ISBN 0-943396-22-0) "Astronomical Formulae for
Calculators".
