Sonbas (Adiyaman Univ.),\nM. Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-142 s to T+641 s (when the burst was in the BAT FOV)\nfrom the recent telemetry downlink, we report further analysis of BAT GRB 181125A\n(trigger #873433) (Sonbas et al., GCN Circ. 23448).\nThe BAT ground-calculated position is\nRA, Dec = 268.391, -2.634 deg which is\n  RA(J2000)  =  17h 53m 33.8s\n  Dec(J2000) = -02d 38' 01.2\"\nwith an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 69%.\n\nThe mask-weighted light curve shows a single-peaked structure that starts\nand peaks at ~T0, and ends at ~T+11 s. T90 (15-350 keV) is 10.5 +- 5.0 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-0.18 to T+11.24 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.57 +- 0.31.  The fluence in the 15-150 keV band is 3.3 +- 0.6 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.24 sec in the 15-150 keV band\nis 1.5 +- 0.3 ph/cm2/sec.  All the quoted errors are at the 90% confidence\nlevel.\n\nThe results of the batgrbproduct analysis are available at\nhttp://gcn.gsfc.nasa.gov/notices_s/873433/BA/",
