TITLE: GCN CIRCULAR NUMBER: 11584 SUBJECT: GRB 110119A: Swift-BAT refined analysis DATE: 11/01/20 04:33:59 GMT FROM: Scott Barthelmy at NASA/GSFC W. H. Baumgartner (GSFC/UMBC), S. D. Barthelmy (GSFC), J. R. Cummings (GSFC/UMBC), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), C. B. Markwardt (GSFC), D. M. Palmer (LANL), T. Sakamoto (GSFC/UMBC), M. Stamatikos (OSU), E. Troja (NASA/GSFC/ORAU), J. Tueller (GSFC), T. N. Ukwatta (GWU) (i.e. the Swift-BAT team): Using the data set from T-240 to T+713 sec from the recent telemetry downlink, we report further analysis of BAT GRB 110119A (trigger #442978) (Troja, et al., GCN Circ. 11581). The BAT ground-calculated position is RA, Dec = 348.589, 5.982 deg, which is RA(J2000) = 23h 14m 21.3s Dec(J2000) = +05d 58' 54.3" with an uncertainty of 1.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 100%. The mask-weighted light curve shows a cluster of 4 or 5 overlapping peaks starting at ~T-90 sec and ending at ~T+90 sec, then a second cluster of 2 or 3 peaks starting at ~T+110 sec and ending at ~T+260 sec. T90 (15-350 keV) is 208 +- 13 sec (estimated error including systematics). The time-averaged spectrum from T-86.4 to T+215.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.44 +- 0.05. The fluence in the 15-150 keV band is 7.0 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+33.16 sec in the 15-150 keV band is 2.2 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
