Ukwatta (MSU)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-240 to T+962 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 140626A (trigger #602604)\n(Cummings, et al., GCN Circ. 16456).  The BAT ground-calculated position is\nRA, Dec = 77.163, -82.625 deg which is\n    RA(J2000)  =  05h 08m 39.1s\n    Dec(J2000) = -82d 37' 29.5\"\nwith an uncertainty of 1.5 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n\nThe mask-weighted light curve shows a double-peaked structure.  The first peak \nextends from T-10 sec to T+0 sec, while the second, comparably-sized peak \nextends from T+0 sec to T+10 sec. T90 (15-350 keV) is 16.4 +- 1.4 sec (estimated \nerror including systematics).\n\nThe time-averaged spectrum from T-8.94 to T+9.08 sec is best fit by a power law\nwith an exponential cutoff.  This fit gives a photon index 0.61 +- 0.88,\nand Epeak of 44.7 +- 9.5 keV (chi squared 45.83 for 56 d.o.f.).  For this\nmodel the total fluence in the 15-150 keV band is 3.6 +- 0.5 x 10^-7 erg/cm2\nand the 1-sec peak flux measured from T+5.68 sec in the 15-150 keV band is\n0.7 +- 0.1 ph/cm2/sec.  A fit to a simple power law gives a photon index\nof 1.91 +- 0.17 (chi squared 54.28 for 57 d.o.f.).  All the quoted errors\nare at the 90% confidence level.\n\nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/602604/BA/",
