Description of the Galilean satellites of Jupiter ephemerides.


Each line contains ephemerides for a single moment of time. The interval of time
between the moments makes 6 hours.

In first five columns the moment of time is placed (year, month, day, hour, modified
Julian day). The following two columns contain the information about the apparent
distance between Moon and Jupiter, and the fraction of the lunar disk that is
illuminated by the Sun (100% is a Full Moon).

Following column (beginning from the 8th) corresponds to a pair "star- satellite".
One column may contain data for different pairs "star- satellite" if their close
encounters do no coincide in time. Numbers of satellites and stars, to which
apparent angular distances relate, are given in the first line of the column
segment. The mutual angular distances between star and satellite are given in
arcminutes.
