Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 100702A (trigger #426438)\n(Siegel, et al., GCN Circ. 10916).  The BAT ground-calculated position is\nRA, Dec = 245.693, -56.549 deg which is \n   RA(J2000)  =  16h 22m 46.4s \n   Dec(J2000) = -56d 32' 57.4\" \nwith an uncertainty of 1.4 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 61%.\n \nThe mask-weighted light curve shows a FRED-like pulse starting at T_zero to \n~T+0.25 sec.  There is a possible weak pulse emission at T-0.25 sec.  \nT90 (15-350 keV) is 0.16 +- 0.03 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T+0.036 to T+0.236 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.54 +- 0.15.  The fluence in the 15-150 keV band is 1.2 +- 0.1 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.36 sec in the 15-150 keV band\nis 2.0 +- 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/426438/BA/",
