Zhang (PSU) (i.e. the Swift-BAT team):\n \nUsing the data set from T-61 to T+243 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 120703A (trigger #525671)\n(Zhang, et al., GCN Circ. 13408).  The BAT ground-calculated position is\nRA, Dec = 339.353, -29.726 deg, which is \n   RA(J2000)  =  22h 37m 24.7s \n   Dec(J2000) = -29d 43' 34.9\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 50%.\n \nThe mask-weighted light curve shows the burst started at ~T-45 sec with a weak\npulse with a width of about 20 sec.  The burst continues with a moderate increase\nto a strong central pulse from T-0.2 to T+1.0 sec, and then a decay back\nto baseline at ~T+45 sec.  T90 (15-350 keV) is 25.2 +- 4.3 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T-7.27 to T+32.60 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.51 +- 0.06.  The fluence in the 15-150 keV band is 3.5 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.06 sec in the 15-150 keV band\nis 10.5 +- 0.4 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/525671/BA/",
