Simpson (PSU),\nM. Stamatikos (OSU), (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 201001A (trigger #998344)\n(Simpson, et al., GCN Circ. 28539).  The BAT ground-calculated position is\nRA, Dec = 110.050, -2.213 deg which is \n  RA(J2000)  =  07h 20m 12.0s \n  Dec(J2000) = -02d 12' 48.3\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 38%.\n\nThe mask-weighted light curve shows a broad single peak of duration roughly \n20 seconds, from ~T-5 to ~T+15 sec.  T90 (15-350 keV) is 15.2 +- 2.7 sec (estimated \nerror including systematics).\n\nThe time-averaged spectrum from T-4.02 to T+12.98 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n0.96 +- 0.23.  The fluence in the 15-150 keV band is 7.6 +- 1.1 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+10.79 sec in the 15-150 keV band\nis 1.0 +- 0.3 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/998344/BA/",
