The T90 and T50 \ndurations measured by the HXM2 data are 24.0 +/- 2.0 sec and \n14.0 +/- 2.0 sec (7-100 keV), respectively.  The highest significance\nduring the burst is 4.6 sigma at T+15.8 sec with HXM2 data in the 7 - 10 keV band.\n\nThe ground-processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1349052973/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at Waseda University.",
