Palmer (LANL),\nT. Sakamoto (AGU), M. Stamatikos (OSU), C. A. Swenson (PSU),\nT. N. Ukwatta (MSU) (i.e. the Swift-BAT team):\n\nUsing the data set from T-239 to T+454 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 130725B (trigger #564028)\n(Swenson, et al., GCN Circ. 15029).  The BAT ground-calculated position is\nRA, Dec = 214.233, -11.124 deg which is\n     RA(J2000)  =  14h 16m 55.9s\n     Dec(J2000) = -11d 07' 26.3\"\nwith an uncertainty of 1.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 96%.\n\nThe mask-weighted light curve shows a single FRED burst peaking at T+1 sec\nand decaying to baseline by about T+8 sec. T90 (15-350 keV) is 10.0 +- 3.6\nsec (estimated error including systematics).\n\nThe time-averaged spectrum from T-0.3 to T+12.8 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.23 +- 0.17.  The fluence in the 15-150 keV band is 3.9 +- 0.4 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.29 sec in the 15-150 keV band\nis 2.2 +- 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/564028/BA/",
