Tueller (GSFC)\non behalf of the Swift-BAT team:\n\nUsing the data set from T-120 to T+302 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 060807 (trigger #223217)\n(De Pasquale, et al., GCN Circ. 5409).  The BAT ground-calculated position\nis (RA,Dec) = 252.505, 31.597 deg {16h 50m 1.3s, 31d 35' 48.0\"} (J2000)\n+- 1.7 arcmin, (radius, sys+stat, 90% containment).  The partial coding was 69%.\n \nThe mask-weighted lightcurve shows a roughly triangular shaped peak\nstarting at T-50, peaking at T+0, and ending at T+30 sec.\nT90 (15-350 keV) is 34 +- 4 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-16.5 to T+24.7 is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum\nis 1.57 +- 0.20.  The fluence in the 15-150 keV band is\n7.3 +- 0.9 x 10^-7 erg/cm2.  The 1-sec peak photon flux measured\nfrom T-0.14 sec in the 15-150 keV band is 0.8 +- 0.2 ph/cm2/sec.\nAll the quoted errors are at the 90% confidence level.",
