Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-61 to T+233 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 100807A (trigger #431128)\n(Grupe, et al., GCN Circ. 11067).  The BAT ground-calculated position is\nRA, Dec = 55.283, 67.665 deg, which is \n   RA(J2000)  =  03h 41m 07.9s \n   Dec(J2000) = +67d 39' 54.2\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 37%.\n \nThe mask-weighted light curve a single peak starting around T-20 sec,\npeaking at ~T+0, and ending around T+20 sec.  T90 (15-350 keV) is\n7.9 +- 1.6 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-6.1 to T+3.1 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.32 +- 0.23.  The fluence in the 15-150 keV band is 3.4 +- 0.5 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.35 sec in the 15-150 keV band\nis 1.8 +- 0.2 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/431128/BA/",
