No CGBM on-board trigger occurred at the time\nof the event.  Based on the LIGO localization sky map (LIB.fits.gz),\nnone of the probability area was in the field-of-view of the CGBM/HXM.\nHowever, 13.4% of the summed probability was inside the field-of-view\nof the CGBM/SGM.\n\nBased on the analysis of the light curve data with 0.125 sec time resolution\nfrom -60 sec to 60 sec from the trigger time, we found no significant excess\naround the trigger time in either the HXM (7-3000 keV) or the SGM (40 keV -28 MeV)\ndata.\n\nThe CALET Calorimeter (CAL) was operating in low energy trigger mode at the\ntrigger time of G298389.  However, no LIGO high probability region was included\nin the CAL's field of view at the time of the trigger.",
