Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+962 sec from the recent telemetry\ndownlink,\nwe report further analysis of BAT GRB 081104 (trigger #333666)\n(Parsons, et al., GCN Circ. 8473).  The BAT ground-calculated position is\nRA, Dec = 100.500, -54.722 deg which is\n   RA(J2000)  =  06h 42m 00.0s\n   Dec(J2000) = -54d 43' 17.4\"\nwith an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 32%.\n \nThe BAT mask-weighted light curve shows a single FRED peak.\nT90 (15-350 keV) is 59.1 +- 13.9 sec (estimated error including\nsystematics).\n \nThe time-averaged spectrum from T-23.5 to T+51.2 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.00 +- 0.14.  The fluence in the 15-150 keV band is 2.0 +- 0.2 x 10^-06\nerg/cm2.\nThe 1-sec peak photon flux measured from T+13.54 sec in the 15-150 keV band\nis 1.0 +- 0.3 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/333666/BA/",
