Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+721 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 120514A (trigger #522197)\n(Mangano, et al., GCN Circ. 13289).  The BAT ground-calculated position is\nRA, Dec = 283.002, -4.258 deg which is \n   RA(J2000)  =  18h 52m 00.4s \n   Dec(J2000) = -04d 15' 28.6\" \nwith an uncertainty of 1.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 61%.\n \nThe mask-weighted light curve shows 3 main peaks.  The first starts at ~T-40 sec,\nand peaks at ~T+1 sec.  The second overlaps the tail of the first and peaks at ~T+52\nand ends at ~T+115 sec.  The third peak starts at ~T+120 sec, peaks at ~T+150 sec\nand ends at ~T+200 sec.  At the 2-sigma level, there is possible precursor emission\nfrom ~T-160 to T-80 sec, and a possible forth peak from ~T+260 to ~T+420 sec.\nT90 (15-350 keV) is 164.4 +- 5.8 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-8.75 to T+165.55 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.62 +- 0.10.  The fluence in the 15-150 keV band is 2.8 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.22 sec in the 15-150 keV band\nis 1.9 +- 0.2 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/522197/BA/",
