Markwardt (GSFC), D. M. Palmer (LANL),\nT. Sakamoto (AGU), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (LANL)\n(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 141004A (trigger #614390)\n(D'Elia, et al., GCN Circ. 16878).  The BAT ground-calculated position is\nRA, Dec = 76.721, 12.828 deg, which is \n   RA(J2000)  =  05h 06m 53.0s \n   Dec(J2000) = +12d 49' 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 peak starting with a weak\nemission at T-1 sec, the FRED peak starting at T_0.0, peaking at T+0.1 sec,\nand returning to baseline at ~T+20 sec.  T90 (15-350 keV) is 3.92 +- 1.07 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T-0.84 to T+5.34 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.86 +- 0.08.  The fluence in the 15-150 keV band is 6.7 +- 0.3 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.06 sec in the 15-150 keV band\nis 6.1 +- 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/614390/BA/",
