CONTENTS OF THE DIRECTORY

This directory contains the observational data of the mutual events of the
Galilean satellites of Jupiter occurring in 1985. One will find:

1) - The file phemu85.dat 

     Contents: 
       - 167 observations of 64 events observed from may 1985 until december 
         1985,
       - these events are observed from 25 sites, 
       - the file provides one record for each individual observation of an 
         event.
