Palmer (LANL), T. Sakamoto (AGU),\nM. Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+962 sec from the recent telemetry downlinks,\nwe report further analysis of BAT GRB 160625A (trigger #701503)\n(Maselli, et al., GCN Circ. 19577).  The BAT ground-calculated position is\nRA, Dec = 176.939, -65.142 deg, which is \n   RA(J2000)  =  11h 47m 45.3s \n   Dec(J2000) = -65d 08' 30.9\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 57%.\n \nThe mask-weighted light curve shows at least 7 peaks, the first starting\nat ~T-35 sec, the brightest peak at ~T+36 sec, and the last peak ending at ~T+70 sec.\nThe peak mentioned in GCN Circ 19577 at T+170 sec is due to GRB 160625B (as suggested\nby Kann, Circ 19579) and confirmed by our analysis.\nT90 (15-350 keV) is 53.9 +- 3.1 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-15.04 to T+47.41 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.08 +- 0.07.  The fluence in the 15-150 keV band is 3.3 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+35.07 sec in the 15-150 keV band\nis 3.0 +- 0.2 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/701503/BA/",
