Stamatikos (OSU), E. Troja (NASA/GSFC/UMCP),\nT. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+962 sec from the recent telemetry\ndownlink,\nwe report further analysis of BAT GRB 191001B (trigger #927345)\n(Troja et al., GCN Circ. 25902).  The BAT ground-calculated position is\nRA, Dec = 86.423, -15.880 deg which is\n   RA(J2000)  =  05h 45m 41.5s\n   Dec(J2000) = -15d 52' 48.3\"\nwith an uncertainty of 3.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 33%.\n\nThe mask-weighted light curve shows a multi-peaked structure that starts\nat ~T-10 s and ends at ~T+130 s. T90 (15-350 keV) is 108.9 +- 15.1 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-8.77 to T+126.11 sec is best fit by a\nsimple\npower-law model.  The power law index of the time-averaged spectrum is\n1.58 +- 0.11.  The fluence in the 15-150 keV band is 4.6 +- 0.3 x 10^-6\nerg/cm2.\nThe 1-sec peak photon flux measured from T+20.44 sec in the 15-150 keV band\nis 1.8 +- 0.4 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/927345/BA/",
