Stamatikos (OSU),\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 150626A (trigger #646603)\n(Roegiers, et al., GCN Circ. 17960).  The BAT ground-calculated position is\nRA, Dec = 111.353, -37.803 deg which is \n  RA(J2000)  =  07h 25m 24.8s \n  Dec(J2000) = -37d 48' 10.8\" \nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 37%.\n\nThe mask-weighted lightcurve shows overlapping peaks starting at\n~T-35 sec, peaking at ~T+2 sec, and ending at ~T+140 sec.  T90 (15-350 keV) \nis 144 +- 66 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-47.30 to T+144.70 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.11 +- 0.19.  The fluence in the 15-150 keV band is 1.8 +- 0.2 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T+8.20 sec in the 15-150 keV band\nis 0.4 +- 0.3 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/646603/BA/",
