Using the CAL data, we have searched for\ngamma-ray events in the 10-100 GeV band within the time interval\nT0 +/- 60 sec and found no candidates.\nThe 90% upper limit of CAL is 1.0x10^-4 erg/cm2/s (10-100 GeV) when\nthe summed LIGO-Virgo probability reaches 5%.\nThe CAL FOV was centered at RA=131.3 deg, Dec=-43.6 deg at T0.",
