Sakamoto (AGU), T. N. Ukwatta (LANL)\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 170127A (trigger #735326)\n(Markwardt et al., GCN Circ. 20538).  The BAT ground-calculated position is\nRA, Dec = 174.382, -45.827 deg which is\n   RA(J2000)  =  11h 37m 31.6s\n   Dec(J2000) = -45d 49' 38.6\"\nwith an uncertainty of 2.4 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 97%.\n\nThe mask-weighted light curve shows some weak overlapping pulses that\nstarts at ~T-5 s and ends at ~T+65 s. T90 (15-350 keV) is\n62.26 +- 10.39 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-4.65 to T+64.51 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.10 +- 0.30.  The fluence in the 15-150 keV band is 5.2 +- 1.0 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+7.31 sec in the 15-150 keV band\nis 0.3 +- 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\nhttp://gcn.gsfc.nasa.gov/notices_s/735326/BA/",
