Markwardt (GSFC), D. M. Palmer (LANL),\nT. Sakamoto (AGU), M. Stamatikos (OSU) (i.e. the Swift-BAT team):\n \nUsing the data set from T-240 to T+877 sec from the recent telemetry downlinks,\nwe report further analysis of BAT GRB 160716A (trigger #704572)\n(Hagen, et al., GCN Circ. 19716).  The BAT ground-calculated position is\nRA, Dec = 190.502, -61.364 deg, which is \n   RA(J2000)  =  12h 42m 00.6s \n   Dec(J2000) = -61d 21' 51.8\" \nwith an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 75%.\n \nThe mask-weighted light curve shows at least 2 overlapping peaks starting\nat ~T-5sec, peaking at ~T+1 sec, and ending at ~T+20 sec.\nT90 (15-350 keV) is 6.39 +- 0.57 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-0.43 to T+6.73 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n2.29 +- 0.30.  The fluence in the 15-150 keV band is 1.8 +- 0.3 x 10^-07 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.95 sec in the 15-150 keV band\nis 0.8 +- 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/704572/BA/",
