Using the CAL data,\nwe have searched for gamma-ray events in the 10-100 GeV band \nfrom -60 sec to +60 sec from the GW trigger time and found no \ncandidates. There is no significant overlap with the LVC high \nprobability localization region at T0+-60 sec.  The CAL FOV was\ncentered at RA=349.9 deg, Dec=-16.6 deg at T0.",
