Tueller (GSFC)\non behalf of the Swift-BAT team:\n\nUsing the data set from T-240 to T+963 sec from recent telemetry downlinks,\nwe report further analysis of BAT GRB 060801 (trigger #222154)\n(Racusin, et al., GCN Circ. 5378).  The BAT ground-calculated position is\nRA,Dec = 212.987, 16.988 deg {14h 11m 56.9s, 16d 59' 17.4\"} (J2000)\n+- 1.8 arcmin, (radius, sys+stat, 90% containment).  This burst\nwas in the fully-coded field-of-view.\n \nThe mask-weighted lightcurve shows two overlapping peaks.  The first,\nand brighter of the two, starts at T+0.0 sec and peaks at ~T+0.06 sec.\nThe second peaks at ~T+0.50 sec and ends at ~T+0.7 sec.  At the ~2-sigma\nlevel, there is a possible short peak at ~T+1.3 sec.  T90 (15-350 keV)\nis 0.5 +- 0.1 sec (estimated error including systematics).\nThere is no obvious emission, soft or otherwise, in the T+10 to T+200 sec\ntime range.\n \nThe time-averaged spectrum from T+0.0 to T+0.6 is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum\nis 0.47 +- 0.24.  The fluence in the 15-150 keV band is\n8.1 +- 1.0 x 10^-8 erg/cm2.  The 1-sec peak photon flux measured\nfrom T-0.18 sec in the 15-150 keV band is 1.3 +- 0.2 ph/cm2/sec.\nAll the quoted errors are at the 90% confidence level. \n\nThe lag for this burst is -0.008 +/- 0.008 sec, between the 25-50 keV\nand 100-350 keV bands.",
