Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+422 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 071025 (trigger #295301)\n(Pagani, et al., GCN Circ. 6986).  The BAT ground-calculated position is\nRA, Dec = 355.065, 31.784 deg, which is \n   RA(J2000)  = 23h 40m 15.6s \n   Dec(J2000) = 31d 47' 3\" \nwith an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 48%.\n \nThe mask-weighted light curve shows a broad peak composed of several overlapping\nsubpeaks.  It starts at ~T+0 sec, peaks around T+90 sec, and slowly decays\nout to at least T+422 sec.  Because of an observing constraint, the s/c had to slew \noff the burst location, and so we do not have any information on the continuation\nof the emission beyond the T+422 sec limit.  T90 (15-350 keV) is at least 109 +- 2 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T+38.5 to T+193.8 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.79 +- 0.05.  The fluence in the 15-150 keV band is 6.5 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+80.17 sec in the 15-150 keV band\nis 1.6 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel.",
