Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+464 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 130529A (trigger #556930)\n(D'Elia, et al., GCN Circ. 14717).  The BAT ground-calculated position is\nRA, Dec = 24.274, -64.143 deg, which is \n   RA(J2000)  =  01h 37m 05.7s \n   Dec(J2000) = -64d 08' 34.8\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n \nThe mask-weighted light curve shows the burst starting at ~T-20 sec,\npeaking at about T+80 sec, and ending at ~T+260 sec.\nT90 (15-350 keV) is 128 +- 35 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-15.02 to T+150.62 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.56 +- 0.17.  The fluence in the 15-150 keV band is 1.4 +- 0.2 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T+64.28 sec in the 15-150 keV band\nis 0.5 +- 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/556930/BA/",
