TITLE: GCN CIRCULAR NUMBER: 20049 SUBJECT: GRB 161014A: Swift-BAT refined analysis DATE: 16/10/15 14:04:09 GMT FROM: Takanori Sakamoto at AGU S. D. Barthelmy (GSFC), J. R. Cummings (GSFC/UMBC), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (GSFC/UMBC), C. B. Markwardt (GSFC), D. M. Palmer (LANL), J. L. Racusin (NASA/GSFC), T. Sakamoto (AGU), 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 downlink, we report further analysis of BAT GRB 161014A (trigger #717500) (Racusin, et al., GCN Circ. 20035). The BAT ground-calculated position is RA, Dec = 332.626, 7.467 deg which is RA(J2000) = 22h 10m 30.1s Dec(J2000) = +07d 28' 01.9" with an uncertainty of 1.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 13%. The mask-weighted light curve shows a complex structure starting at T-10 sec and ending at T+15 sec. T90 (15-350 keV) is 18.3 +- 2.8 sec (estimated error including systematics). The time-averaged spectrum from T-9.1 to T+12.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.47 +- 0.15. The fluence in the 15-150 keV band is 1.9 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+0.10 sec in the 15-150 keV band is 2.9 +- 0.6 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
