Tueller (GSFC)\non behalf of the Swift-BAT team:\n\nUsing the data set from T-239.0 to T+595.8 sec from the recent telemetry \ndownlink,\nwe report further analysis of BAT GRB 061004 (trigger #232339)  \n(Ziaeepour, et\nal., GCN Circ. 5691).  The BAT ground-calculated position is RA,Dec = \n97.795,\n-45.903 deg {6h 31m 10.8s, -45d 54' 9.8\"} (J2000) +- 0.8 arcmin, (radius,\nsys+stat, 90% containment).  The partial coding was 98%.\n\nThe light curve shows a single peak, extending out to T+8 seconds.\nT90 (15-350 keV) is 6.2 +- 0.3 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T+0.2 to T+8.1 is best fit by a simple \npower-law\nmodel. The power law index of the time-averaged spectrum is 1.81 +- 0.10.\nThe fluence in the 15-150 keV band is 5.7 +- 0.3 x 10-07 erg/cm2.\nThe 1-sec peak photon flux measured from T+2.67 sec in the 15-150 keV\nband is 2.5 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90%\nconfidence level.",
