Sakamoto (AGU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-239 to T+963 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 251014D (trigger #1404126)\n(Klingler, et al., GCN Circ. 42274).  The BAT ground-calculated position is\nRA, Dec = 323.933, -41.873 deg which is \n   RA(J2000)  =  21h 35m 43.9s \n   Dec(J2000) = -41d 52' 23.0\" \nwith an uncertainty of 2.7 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 49%.\n \nThe mask-weighted BAT light curve shows a main emission followed by weaker \nemission. T90 (15-350 keV) is 286.98 +- 70.09 sec (estimated error including \nsystematics).\n \nThe time-averaged spectrum from T+0.39 to T+310.10 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.74 +- 0.38.  The fluence in the 15-150 keV band is 1.0 +- 0.2 x 10^-06 erg/cm2.\nThe 1-sec peak photon flux measured from T+5.18 sec in the 15-150 keV band\nis 0.5 +- 0.2 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/1404126\n",
