Palmer (LANL), T. Sakamoto (AGU),\nM. Stamatikos (OSU), T. N. Ukwatta (LANL)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+962 sec from the recent telemetry downlinks,\nwe report further analysis of BAT GRB 160123A (trigger #671447)\n(Malesani, et al., GCN Circ. 18926).  The BAT ground-calculated position is\nRA, Dec = 150.277, -33.790 deg, which is \n   RA(J2000)  =  10h 01m 06.4s \n   Dec(J2000) = -33d 47' 23.1\" \nwith an uncertainty of 1.6 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 68%.\n \nThe mask-weighted light curve shows one peak starting at ~T-15 sec, \npeaking at ~T+0.5 sec, and ending at ~T+10 sec.\nT90 (15-350 keV) is 3.95 +- 0.62 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-2.05 to T+3.00 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.51 +- 0.16.  The fluence in the 15-150 keV band is 3.5 +- 0.4 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.01 sec in the 15-150 keV band\nis 1.3 +- 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/671447/BA/",
