Palmer (LANL), T. Sakamoto (AGU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-315 to T+934 sec from the recent telemetry downlinks,\nwe report further analysis of BAT GRB 151205A (trigger #666352)\n(Cummings, et al., GCN Circ. 18657).  The BAT ground-calculated position is\nRA, Dec = 229.291, 35.767 deg, which is\n   RA(J2000)  =  15h 17m 09.7s \n   Dec(J2000) = +35d 46' 01.7\" \nwith an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 93%.\n \nThe mask-weighted light curve shows several overlapping peaks starting at\n~T-10 sec, peaking at ~T+3 sec, with a long tail out to T+170 sec.\nT90 (15-350 keV) is 62.8 +- 12.3 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-4.0 to T+69.5 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.17 +- 0.13.  The fluence in the 15-150 keV band is 1.4 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.98 sec in the 15-150 keV band\nis 0.6 +- 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/666352/BA/",
