Parsotan (GSFC/UMBC),\n\nT. Sakamoto (AGU), (i.e. the Swift-BAT team):\n\n\n\nUsing the data set from T-239 to T+941 sec from the recent telemetry\ndownlink,\n\nwe report further analysis of BAT GRB 221201A (trigger #1142847)\n\n(Troja et al., GCN Circ. 32998).  The BAT ground-calculated position is\n\nRA, Dec = 266.903, -68.230 deg which is\n\n   RA(J2000)  =  17h 47m 36.6s\n\n   Dec(J2000) = -68d 13' 48.2\"\n\nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\n\nThe partial coding was 51%.\n\n\n\nThe mask-weighted light curve shows a single peaked pulse.\n\nT90 (15-350 keV) is 33.71 +- 2.03 sec (estimated error including\nsystematics).\n\n\n\nThe time-averaged spectrum from T-20.88 to T+22.92 sec is best fit by a\nsimple\n\npower-law model.  The power law index of the time-averaged spectrum is\n\n1.63 +- 0.05.  The fluence in the 15-150 keV band is 8.6 +- 0.2 x 10^-06\nerg/cm2.\n\nThe 1-sec peak photon flux measured from T-13.51 sec in the 15-150 keV band\n\nis 11.2 +- 0.6 ph/cm2/sec.  All the quoted errors are at the 90% confidence\n\nlevel.\n\n\n\nThe results of the batgrbproduct analysis are available at\n\nhttp://gcn.gsfc.nasa.gov/notices_s/1142847/BA/",
