The T90 and T50 durations measured by the SGM data are\n42.8 +- 2.5 sec and 24.6 +- 3.5 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1242285834/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
