Description of the main satellites of Saturn (S1-S8) 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 Saturn, 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 apparent angular
distances "star- satellite". One column may contain data for different pairs "star-
satellite" if their close encounters do no coincide in time. Numbers of stars and
satellites to which apparent angular distances relate, are given in the two
lines above of the column segment. The mutual angular distances between star and
satellite are given in arcminutes.
