Ukwatta (GWU) (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 081016B (trigger #331856)\n(Page, et al., GCN Circ. 8381).  The BAT ground-calculated position is\nRA, Dec = 14.582, -43.536 deg which is\n  RA(J2000)  =  00h 58m 19.8s\n  Dec(J2000) = -43d 32' 07.9\"\nwith an uncertainty of 2.3 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 98%.\n\nThe BAT mask-weighted light curve showed a single peak of duration ~2.5 \nseconds.\nT90 (15-350 keV) is 2.6 +- 0.8 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-0.0 to T+3.0 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n0.92 +- 0.32.  The fluence in the 15-150 keV band is 9.9 +- 1.8 x 10-08 \nerg/cm2.\nThe 1-sec peak photon flux measured from T+0.50 sec in the 15-150 keV band\nis 0.5 +- 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/331856/BA/",
