Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-240 to T+963 sec from the recent\ntelemetry downlink, we report further analysis of BAT\nGRB 151215A (trigger #667392) (Gibson, et al., GCN\nCirc. 18691). The BAT ground-calculated position is\nRA, Dec = 93.622, 35.529 deg which is\n   RA(J2000)  =  06h 14m 29.3s\n   Dec(J2000) = +35d 31' 45.0\"\nwith an uncertainty of 2.8 arcmin, (radius, sys+stat,\n90% containment). The partial coding was 51%.\n\nThe mask-weighted light curve shows a multi-peak episode\nstarting ~T-15 sec, highest peak at ~T+0 sec, and the\nepisode ends around ~T+5 sec. T90 (15-350 keV)\nis 17.8 +- 1.0 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-15.46 to T+3.13 sec is\nbest fit by a simple power-law model. The power law index\nof the time-averaged spectrum is 1.99 +- 0.33. The fluence\nin the 15-150 keV band is 3.1 +- 0.7 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.16 sec in\nthe 15-150 keV band is 1.6 +- 0.2 ph/cm2/sec. All the\nquoted errors are at the 90% confidence level.\n\nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/667392/BA/",
