Sakamoto (GSFC/UMBC), M. Stamatikos (OSU),\nE. Troja (NASA/GSFC/ORAU), J. Tueller (GSFC), T. N. Ukwatta (GWU)\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 100802A (trigger #430603)\n(Troja, et al., GCN Circ. 11031).  The BAT ground-calculated position is\nRA, Dec = 2.482, 47.752 deg, which is \n   RA(J2000)  =  00h 09m 55.6s \n   Dec(J2000) = +47d 45' 05.5\" \nwith an uncertainty of 1.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 84%.\n \nThe mask-weighted light curve shows a FRED peak starting at ~T-7 sec and\npeaking at ~T+1sec.  There is a second peak on the tail of the first \nat ~T+90 sec.  There is also a long peak starting around T+250, peaking\nat ~T+450 sec, and ending at ~T+700 sec.  T90 (15-350 keV) is 487 +- 30 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T-3.3 to T+531.7 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.85 +- 0.10.  The fluence in the 15-150 keV band is 3.6 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.08 sec in the 15-150 keV band\nis 0.9 +- 0.1 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/430603/BA/",
