Markwardt (GSFC), D. M. Palmer (LANL),\nT. Sakamoto (AGU), M. Stamatikos (OSU),\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-61 to T+242 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 160412A (trigger #682522)\n(Gibson, et al., GCN Circ. 19298).  The BAT ground-calculated position is\nRA, Dec = 33.074, -67.636 deg, which is \n   RA(J2000)  =  02h 12m 17.7s \n   Dec(J2000) = -67d 38' 08.8\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 75%.\n \nThe mask-weighted light curves shows several overlapping peaks starting at\n~T-10 sec, peaking at ~T+15 sec, and ending at ~T+70 sec.\nT90 (15-350 keV) is 31.6 +- 4.0 sec (estimated error including systematics).\n \nThe time-averaged spectrum from T-3.35 to T+40.18 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.88 +- 0.08.  The fluence in the 15-150 keV band is 1.9 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+14.40 sec in the 15-150 keV band\nis 1.6 +- 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/682522/BA/",
