Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-60 to T+243 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 130627A (trigger #559132)\n(Oates, et al., GCN Circ. 14933).  The BAT ground-calculated position is\nRA, Dec = 184.415, -37.114 deg which is\n  RA(J2000)  =  12h 17m 39.7s\n  Dec(J2000) = -37d 06' 51.8\"\nwith an uncertainty of 2.8 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 20%.\n\nThe mask-weighted light curve shows a single peak starting at ~T-4 sec,\npeaking at ~T+2 sec, and ending at ~T+26.\nT90 (15-350 keV) is 30.8 +- 12.3 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-5.2 to T+33.6 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.84 +- 0.32.  The fluence in the 15-150 keV band is 9.1 +- 1.9 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T+1.88 sec in the 15-150 keV band\nis 1.8 +- 0.5 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/559132/BA/",
