Palmer (LANL), T. Sakamoto (GSFC/UMBC),\nM. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+963 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 120815A (trigger #531003)\n(Pagani, et al., GCN Circ. 13645).  The BAT ground-calculated position is\nRA, Dec = 273.976, -52.125 deg, which is \n   RA(J2000)  =  18h 15m 54.4s \n   Dec(J2000) = -52d 07' 29.0\" \nwith an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 28%.\n \nThe mask-weighted light curve shows a FRED pulse starting at ~T-0.3 sec,\npeaking at ~T+0.5 sec, and ending at ~T+30 sec.  T90 (15-350 keV) is\n9.7 +- 2.5 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-0.24 to T+11.97 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.29 +- 0.23.  The fluence in the 15-150 keV band is 4.9 +- 0.7 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.17 sec in the 15-150 keV band\nis 2.2 +- 0.3 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel. \n \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/531003/BA/",
