Markwardt (GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), M. Stamatikos (OSU),\nJ. Tueller (GSFC), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 150314A (trigger #634795)\n(Hagen, et al., GCN Circ. 17573).  The BAT ground-calculated position is\nRA, Dec = 126.661, 63.839 deg which is\n  RA(J2000)  =  08h 26m 38.6s\n  Dec(J2000) = +63d 50' 21.0\"\nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 34%.\n\nThe mask-weighted light curve shows a single bright FRED pulse that starts at\n~ T-2 s, peaks at ~T0, and ends at  ~T+13 s. There are some weak extended\nemissions that last till ~ T+100 s. T90 (15-350 keV) is 14.79 +- 2.64 sec (estimated\nerror including systematics).\n\nThe time-averaged spectrum from T-2.17 to T+101.42 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.08 +- 0.03.  The fluence in the 15-150 keV band is 2.2 +- 0.03 x 10^-5 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.06 sec in the 15-150 keV band\nis 38.5 +- 0.9 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/634795/BA/",
