Ukwatta (GWU) \n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+500 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 100625A (trigger #425647)\n(Holland, et al., GCN Circ. 10884).  The BAT ground-calculated position is\nRA, Dec = 15.796, -39.091 deg which is \n   RA(J2000)  =  01h 03m 11.1s \n   Dec(J2000) = -39d 05' 29.3\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n \nThe mask-weighted light curve shows two overlapping peaks starting at ~T-0.1 sec,\npeaking at ~T+0.1 and T+0.2 sec, and ending at ~T+0.3 sec.  There is a weak soft\ntail out to ~T+30 sec.  T90 (15-350 keV) is 0.33 +- 0.03 sec (estimated error\nincluding systematics).\n \nThe time-averaged spectrum from T-0.1 to T+0.3 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n0.90 +- 0.10.  The fluence in the 15-150 keV band is 2.3 +- 0.2 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.37 sec in the 15-150 keV band\nis 2.6 +- 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/425647/BA/",
