Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+130 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 201203A (trigger #1010946)\n(Dichiara et al., GCN Circ. 28985).  The BAT ground-calculated position is\nRA, Dec = 38.055, -26.505 deg which is\n   RA(J2000)  =  02h 32m 13.1s\n   Dec(J2000) = -26d 30' 19.2\"\nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 91%.\n\nThe BAT light curve showed a complex structure with a duration of about ~20 sec.\nT90 (15-350 keV) is 12.18 +- 2.10 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-2.73 to T+12.84 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.78 +- 0.26.  The fluence in the 15-150 keV band is 2.9 +- 0.5 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T+11.49 sec in the 15-150 keV band\nis 0.5 +- 0.1 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/1010946/BA/",
