       - 4411 observations of occultation events of the Galilean  
         satellites since January, 1836 to June, 1972
       - these observations are made from 45 sites,
       - It provides for the observed satellite:
 
	. the type of the event and the O-C from the three ephemerides 
	  SV2(Vu 1977), E-2(Lieske 1980), G-5(Arlot 1980),
	. the time elapsed, TOC, between the first/last contact and the 
	  bissection/mid-event, 
	. the site of observation, 
	. the bibliographic reference with codes.
	. the type of the event and the O-C from the three ephemerides

	. the time elapsed, TOC, between the first/last contact and the 
	  bissection/mid-event, 
	. the site of observation and 
	. the bibliographic reference with codes.
