Stamatikos (OSU) (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 220319A (trigger #1098132)\n(Page et al., GCN Circ. 31769).  The BAT ground-calculated position is\nRA, Dec = 218.139, 61.291 deg which is\n   RA(J2000)  =  14h 32m 33.4s\n   Dec(J2000) = +61d 17' 26.6\"\nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 43%.\n\nThe BAT light curve showed a single-peaked\nstructure with a duration of about 10 sec.\nT90 (15-350 keV) is 6.44 +- 1.54 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-0.36 to T+6.56 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.15 +- 0.28.  The fluence in the 15-150 keV band is 2.3 +- 0.4 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.24 sec in the 15-150 keV band\nis 1.5 +- 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/1098132/BA/",
