Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-61 to T+242 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 131202A (trigger #579982)\n(Kocevski, et al., GCN Circ. 15559).  The BAT ground-calculated position is\nRA, Dec = 344.005, -21.650 deg which is\n    RA(J2000)  =  22h 56m 01.3s\n    Dec(J2000) = -21d 38' 58.9\"\nwith an uncertainty of 2.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 63%.  The mask-weighted light curve shows a pair of\noverlapping peaks covering the period from T-10 to T+40 seconds.\nT90 (15-350 keV) is 30.4 +- 10.9 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-1.62 to T+37.98 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.58 +- 0.26.  The fluence in the 15-150 keV band is 6.1 +- 1.0 x 10^-7erg/cm2.\nThe 1-sec peak photon flux measured from T+1.64 sec in the 15-150 keV band\nis 0.7 +- 0.2 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/579982/BA/",
