Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+962 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 100205 (trigger #411248)\n(Racusin, et al., GCN Circ. 10361).  The BAT ground-calculated position is\nRA, Dec = 141.385, 31.740 deg which is \n   RA(J2000)  =  09h 25m 32.5s \n   Dec(J2000) = +31d 44' 23.7\" \nwith an uncertainty of 2.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 80%.\n \nThe mask-weighted light curve shows a roughly symetric peak starting\nat ~T-15 sec, peaking at ~T+5 sec, and ending at ~T+30 sec.\nT90 (15-350 keV) is 26.0 +- 8 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-12.6 to T+25.6 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.60 +- 0.25.  The fluence in the 15-150 keV band is 4.0 +- 0.7 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+8.12 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/411248/BA/",
