          Note: data1= data on the timing of the mutual events: date of the maximum in UTC and observed magnitude drop (until 1985 occurrence)
                data1= data on the astrometric positions extracted from the mutual events (from 2009 occurrence)
                data2= data of the observed photometric lightcurves; date and magnitude drop for each point
