The T90 and T50\ndurations measured by the SGM data are 5.9 +- 1.0 sec and 2.1 +- 0.2 sec\n(40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1247668851/\n\nThe CALET data used in this analysis are provided by the Waseda CALET\nOperation Center located at the Waseda University.",
