TITLE: GCN CIRCULAR NUMBER: 18604 SUBJECT: GRB 151114A: Swift-BAT refined analysis DATE: 15/11/14 20:49:26 GMT FROM: Scott Barthelmy at NASA/GSFC A. Y. Lien (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 (AGU), M. H. Siegel (PSU), M. Stamatikos (OSU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from the recent telemetry downlinks, we report further analysis of BAT GRB 151114A (trigger #663490) (Siegel, et al., GCN Circ. 18599). The BAT ground-calculated position is RA, Dec = 120.947, -61.033 deg, which is RA(J2000) = 08h 03m 47.4s Dec(J2000) = -61d 01' 58.3" with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 30%. The mask-weighted light curve shows a single peak starting at ~T-4 sec, peaking at ~T0 sec, and ending at ~T+1 sec. T90 (15-350 keV) is 4.86 +- 0.98 sec (estimated error including systematics). The time-averaged spectrum from T-4.26 to T+1.25 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 2.14 +- 0.25. The fluence in the 15-150 keV band is 3.7 +- 0.6 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.06 sec in the 15-150 keV band is 2.9 +- 0.4 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
