The T90 and T50 durations\nmeasured by the SGM data are 5.0 +- 0.7 sec and 3.0 +- 0.9 sec\n(40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1311219774/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
