Palmer (LANL), T. Sakamoto (AGU),\nT. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 151001A (trigger #657286)\n(Stamatikos, et al., GCN Circ. 18373).  The BAT ground-calculated position is\nRA, Dec = 233.722, 10.984 deg which is\n  RA(J2000)  =  15h 34m 53.2s\n  Dec(J2000) = +10d 59' 01.1\"\nwith an uncertainty of 1.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n\nThe mask-weighted light curve shows a single-peaked structure that starts\nat ~T-6 s, peaks at ~T0, end ends at~T+5 s. T90 (15-350 keV) is 8.94 +- 1.07 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-6.28 to T+4.53 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.17 +- 0.11.  The fluence in the 15-150 keV band is 6.7 +- 0.5 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.04 sec in the 15-150 keV band\nis 1.3 +- 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/657286/BA/",
