Using the CAL data,\nwe have searched for gamma-ray events in the 10-100 GeV\nband from -60 sec to +60 sec from the GW trigger time and\nfound no candidates.\nThe 90% upper limit of CAL is 1.2x10^-5 erg/cm^2/s (10-100 GeV) when\nthe summed LIGO-Virgo probability reaches 25%.\nThe CAL FOV was centered at RA= 84.0 deg, DEC= 31.5 deg at T0.",
