Palmer (LANL), T. Sakamoto (AGU),\nT. N. Ukwatta (LANL)  (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 190211A (trigger #888648)\n(Marshall, et al., GCN Circ. 23883).  The BAT ground-calculated position is\nRA, Dec = 196.652, 41.976 deg which is \n   RA(J2000)  =  13h 06m 36.5s \n   Dec(J2000) = +41d 58' 32.1\" \nwith an uncertainty of 2.3 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 26%.\n\nThe mask-weighted light curve shows a a pair of peaks, the first from T-12 to T-5 sec,\nand the second from T-4 to T+2 sec. T90 (15-350 keV) is 12.48 +- 1.46 sec (estimated \nerror including systematics).\n\nThe time-averaged spectrum from T-11.49 to T+1.66 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.51 +- 0.33.  The fluence in the 15-150 keV band is 6.5 +- 1.2 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.56 sec in the 15-150 keV band\nis 1.9 +- 0.4 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/888648/BA/",
