Tueller (GSFC),\n(i.e. the Swift-BAT team):\n \nUsing the data set from T-61 to T+243 sec from the recent telemetry downlink,\nwe report further analysis of BAT GRB 110106B (trigger #441676)\n(Sbarufatti, et al., GCN Circ. 11525).  The BAT ground-calculated position is\nRA, Dec = 134.155, 47.005 deg, which is \n   RA(J2000)  =  08h 56m 37.3s \n   Dec(J2000) = +47d 00' 17.5\" \nwith an uncertainty of 1.2 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 37%.\n \nThe mask-weighted light curve shows 3 main overlapping peaks starting\nat ~T-6 sec and ending at ~T+23 sec.  T90 (15-350 keV) is 24.8 +- 4.8 sec\n(estimated error including systematics).\n \nThe time-averaged spectrum from T-10.8 to T+23.5 sec is best fit by a simple\npower-law model.  The power law index of the time-averaged spectrum is\n1.76 +- 0.11.  The fluence in the 15-150 keV band is 2.0 +- 0.1 x 10^-6 erg/cm2.\nThe 1-sec peak photon flux measured from T+4.87 sec in the 15-150 keV band\nis 2.1 +- 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/441676/BA/",
