Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+800 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 151006A (trigger #657750)\n(Kocevski, et al., GCN Circ. 18398).  The BAT ground-calculated position is\nRA, Dec = 147.426, 70.508 deg which is\n  RA(J2000)  =  09h 49m 42.3s\n  Dec(J2000) = +70d 30' 30.2\"\nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n\nThe mask-weighted light curve shows a FRED-like structure that starts at ~T-5 s,\npeaks at ~ T+1 s, and ends at ~ T+310 s. T90 (15-350 keV) is 203.9 +- 41.6 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-4.9 to T+311.2 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.56 +- 0.06.  The fluence in the 15-150 keV band is 6.9 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.49 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/657750/BA/",
