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 downlink,\nwe report further analysis of BAT GRB 160525B (trigger #687522)\n(Krimm, et al., GCN Circ. 19459).  The BAT ground-calculated position is\nRA, Dec = 149.438, 51.197 deg, which is \n   RA(J2000)  =  09h 57m 45.2s \n   Dec(J2000) = +51d 11' 48.9\" \nwith an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 81%.\n \nThe mask-weighted light curve shows weak emission starting at ~T-1 sec,\nthe main emission from ~T0 to ~T+0.3 sec, and weak emission out to ~T+0.6 sec.\nT90 (15-350 keV) is 0.29 +- 0.05 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T+0.02 to T+0.33 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.89 +- 0.35.  The fluence in the 15-150 keV band is 3.2 +- 0.8 x 10^-8 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.32 sec in the 15-150 keV band\nis 0.9 +- 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/687522/BA/",
