Mingo (U Leicester), D. M. Palmer (LANL),\nT. Sakamoto (AGU), T. N. Ukwatta (LANL) (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 160826A (trigger #709907)\n(Mingo, et al., GCN Circ. 19866).  The BAT ground-calculated position is\nRA, Dec = 183.120, -67.664 deg which is\n    RA(J2000)  =  12h 12m 28.8s\n    Dec(J2000) = -67d 39' 51.7\"\nwith an uncertainty of 2.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n\nThe mask-weighted light curve shows a single, rough FRED-like peak starting\nat T+0 sec, peaking at about T+5 sec and decaying to near background by T+20 \nsec.  This is followed by low-level emission out to about T+70 sec.\nT90 (15-350 keV) is 52.6 +- 14.5 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T+3.85 to T+61.58 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.54 +- 0.29.  The fluence in the 15-150 keV band is 4.9 +- 0.9 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+4.64 sec in the 15-150 keV band\nis 0.4 +- 0.1 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/709907/BA/",
