Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-61 to T+242 sec from the recent telemetry\ndownlink,\nwe report further analysis of BAT GRB 150302A (trigger #633237)\n(Lien, et al., GCN Circ. 17526).  The BAT ground-calculated position is\nRA, Dec = 175.515, 36.852 deg which is\n RA(J2000)  =  11h 42m 03.6s\n Dec(J2000) = +36d 51' 06.3\"\nwith an uncertainty of 2.8 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n\nThe mask-weighted light curve shows a weak single-peaked structure that\nstarts\nat ~ T-1 s, peaks at ~T+3 s, and ends at ~T+20 s. T90 (15-350 keV) is 23.74\n+- 8.79 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-1.14 to T+28.23 sec is best fit by a\nsimple\npower-law model.  The power law index of the time-averaged spectrum is\n1.69 +- 0.33.  The fluence in the 15-150 keV band is 2.6 +- 0.6 x 10^-7\nerg/cm2.\nThe 1-sec peak photon flux measured from T+2.61 sec in the 15-150 keV band\nis 0.4 +- 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/633237/BA/",
