Ukwatta (GWU)\non behalf of the Swift-BAT team:\n \nUsing the data set from T-119 to T+283 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 070529 (trigger #280706)\n(Holland, et al., GCN Circ. 6466).  The BAT ground-calculated position is\nRA, Dec = 283.725, 20.648 deg  which is \n   RA(J2000)  = 18h 54m 54.0s \n   Dec(J2000) = 20d 38' 54\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 16%.\n \nThe mask-weighted lightcurve shows multiple overlapping peaks\nstarting at T_0 and lasting out T+120 sec.  There is a possible (~4 sigma)\n10-sec peak at ~T-55 sec.  T90 (15-350 keV) is 109 +- 3 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T-1.2 to T+120.9 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.38 +- 0.16.  The fluence in the 15-150 keV band is 2.6 +- 0.2 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+2.02 sec in the 15-150 keV band\nis 1.4 +- 0.4 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel.",
