Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-119 to T+54 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 171011A (trigger #778154)\n(Gropp et al., GCN Circ. 21993).  The BAT ground-calculated position is\nRA, Dec = 236.766, -10.064 deg which is\n  RA(J2000)  =  15h 47m 03.7s\n  Dec(J2000) = -10d 03' 50.2\"\nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 63%.\n\nThe mask-weighted light curve shows a single-peaked light curve that\nstarts and peaks at ~ T0, and ends at ~ T+3 s. T90 (15-350 keV) is\n2.27 +- 0.24 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-0.06 to T+2.74 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.68 +- 0.08.  The fluence in the 15-150 keV band is 1.1 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.08 sec in the 15-150 keV band\nis 7.0 +- 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/778154/BA/",
