Tueller (GSFC),\n(i.e. the Swift-BAT team):\n\nUsing the data set from T-180 to T+902 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 140408A (trigger #595141)\n(D'Elia, et al., GCN Circ. 16082).  The BAT ground-calculated position is\nRA, Dec = 290.723, -12.585 deg which is\n   RA(J2000)  =  19h 22m 53.5s\n   Dec(J2000) = -12d 35' 07.7\"\nwith an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 40%.\n\nThe mask-weighted light curve shows a single-pulse structure starts at ~T-1 sec,\npeaks at ~ T+1 sec, and ends at ~T+4 sec. T90 (15-350 keV) is 4.00 +- 1.41 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-0.66 to T+3.34 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.49 +- 0.25.  The fluence in the 15-150 keV band is 3.1 +- 0.5 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T+0.34 sec in the 15-150 keV band\nis 1.2 +- 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/595141/BA/",
