Palmer (LANL), T. Sakamoto (GSFC/UMBC),\nM. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (GWU)\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-60 to T+243 sec from the recent telemetry downlink,\nwe report further analysis of the BAT short hard burst GRB 101219A (trigger #440606)\n(Gelbord, et al., GCN Circ. 11461).  The BAT ground-calculated position is\nRA, Dec = 74.586, -2.527 deg which is \n   RA(J2000)  =  04h 58m 20.7s \n   Dec(J2000) = -02d 31' 37.1\" \nwith an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 94%.\n \nThe mask-weighted light curve shows two overlapping peaks starting at ~T-0.1 sec\nand ending at ~T+0.6 sec.  At the 2-sigma confidence level, there may be\nextended emission out to T+30 sec.  T90 (15-350 keV) is 0.6 +- 0.2 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T-0.0 to T+1.1 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n0.63 +- 0.09.  The fluence in the 15-150 keV band is 4.6 +- 0.3 x 10^-7 erg/cm2.\nThe 1-sec peak photon flux measured from T-0.04 sec in the 15-150 keV band\nis 4.1 +- 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/440606/BA/",
