Ukwatta (MSU)\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 140118A (trigger #584136)\n(Krimm, et al., GCN Circ. 15748).  The BAT ground-calculated position is\nRA, Dec = 330.999, -17.937 deg which is\n    RA(J2000)  =  22h 03m 59.8s\n    Dec(J2000) = -17d 56' 14.1\"\nwith an uncertainty of 1.5 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 41%. The mask-weighted light curve shows a\ndouble-peaked structure of two triangular shaped peaks.  The first\nruns from T-70 to T-20 and the second, stronger peak from T-20 to T+30.\nT90 (15-350 keV) is 84.15 +- 10.79 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-73.61 to T+30.87 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.87 +- 0.13.  The fluence in the 15-150 keV band is 2.6 +- 0.2 x 10^-6 erg/cm2. \nThe 1-sec peak photon flux measured from T+2.98 sec in the 15-150 keV band\nis 1.9 +- 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/584136/BA/",
