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+700 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 180205A (trigger #808625)\n(Evans et al., GCN Circ. 22381).  The BAT ground-calculated position is\nRA, Dec = 126.819, 11.536 deg which is\n  RA(J2000)  =  08h 27m 16.5s\n  Dec(J2000) = +11d 32' 11.1\"\nwith an uncertainty of 1.1 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 50%.\n\nThe mask-weighted light curve shows a multi-peaked structure that starts\nat ~T-7 s and ends at ~T+11 s. The two major peaks occur at ~T-5 s\nand ~T0 s, respectively. T90 (15-350 keV) is 15.5 +- 3.1 sec (estimated\nerror including systematics).\n\nThe time-averaged spectrum from T-7.04 to T+10.87 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.04 +- 0.13.  The fluence in the 15-150 keV band is 1.0 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.20 sec in the 15-150 keV band\nis 3.4 +- 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/808625/BA/",
