Stamatikos (OSU),\nT. N. Ukwatta (LANL) (i.e. the Swift-BAT team):\n\nUsing the data set from T-240 to T+962 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 170711A (trigger #761622)\n(D'Elia, et al., GCN Circ. 21321).  The BAT ground-calculated position is\nRA, Dec = 45.782, 47.845 deg which is\n  RA(J2000)  =  03h 03m 07.7s\n  Dec(J2000) = +47d 50' 41.2\"\nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 100%.\n\nThe mask-weighted light curve shows a single FRED-shaped peak, starting at\nT-2 sec, peaking at T+0 sec and decaying to background by T+6 sec.  This is\npreceded by some weak, soft emission beginning at about T-25 sec.\nT90 (15-350 keV) is 31.3 +- 7.6 sec (estimated error including systematics).\n\nThe time-averaged spectrum from T-31.66 to T+15.37 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.75 +- 0.10.  The fluence in the 15-150 keV band is 1.4 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.02 sec in the 15-150 keV band\nis 4.8 +- 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/761622/BA/",
