Tueller (GSFC),\n(i.e. the Swift-BAT team):\n  \nUsing the data set from T-60 to T+123 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 130822A (trigger #567163)\n(Kocevski, et al., GCN Circ. 15112).  The BAT ground-calculated position is\nRA, Dec = 27.931, -3.193 deg which is\n    RA(J2000)  =  01h 51m 43.4s\n    Dec(J2000) = -03d 11' 34.0\"\nwith an uncertainty of 2.5 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 92%.\n  \nThe mask-weighted light curve shows a single peak.  T90 (15-350 keV) is\n0.04 +- 0.01 sec (estimated error including systematics).\n  \nThe time-averaged spectrum from T-0.004 to T+0.044 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.64 +- 0.29.  The fluence in the 15-150 keV band is 1.3 +- 0.3 x 10^-08 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.48 sec in the 15-150 keV band is\n0.3 +- 0.1 ph/cm2/sec.  All the quoted errors are at the 90% confidence level.\n  \nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/567163/BA/",
