Sakamoto (AGU) (i.e. the Swift-BAT team):\n\nUsing the data set from T-240 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 240805A (trigger #1246907)\n(Dichiara, et al., GCN Circ. 37032).  The BAT ground-calculated position is\nRA, Dec = 190.919, -53.603 deg which is\n   RA(J2000)  =  12h 43m 40.6s\n   Dec(J2000) = -53d 36' 10.3\"\nwith an uncertainty of 0.79 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 31%.\n\nThe mask-weighted BAT light curve shows a complex structure. T90 (15-350 keV) is 37.34 +- 6.22 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-3.936 to T+258.128 sec is best fit by a simple\npower-law model. The power law index of the time-averaged spectrum is\n1.21 +- 0.06.  The fluence in the 15-150 keV band is 8.7 +- 0.3 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T+3.28 sec in the 15-150 keV band\nis 8.0 +- 0.5 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel.\n\nThe results of the batgrbproduct analysis are available at\nhttps://swift.gsfc.nasa.gov/results/batgrbcat/BAT_refined_circular/1246907\n\n\n",
