TITLE: GCN CIRCULAR NUMBER: 42315 SUBJECT: GRB 251014D: Swift-BAT refined analysis DATE: 25/10/16 23:04:28 GMT FROM: Rahul Gupta at NASA GSFC <rahul.gupta@nasa.gov> D. M. Palmer (LANL), S. D. Barthelmy (GSFC), R. Gupta (GSFC), N. J. Klingler (GSFC/UMBC/CRESSTII) H. A. Krimm (NSF), S. Laha (GSFC/UMBC), A. Y. Lien (U Tampa), C. B. Markwardt (GSFC), M. J. Moss (GSFC), T. Parsotan (GSFC), D. Sadaula (GSFC/UMBC), T. Sakamoto (AGU) (i.e. the Swift-BAT team): Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 251014D (trigger #1404126) (Klingler, et al., GCN Circ. 42274). The BAT ground-calculated position is RA, Dec = 323.933, -41.873 deg which is RA(J2000) = 21h 35m 43.9s Dec(J2000) = -41d 52' 23.0" with an uncertainty of 2.7 arcmin, (radius, sys+stat, 90% containment). The partial coding was 49%. The mask-weighted BAT light curve shows a main emission followed by weaker emission. T90 (15-350 keV) is 286.98 +- 70.09 sec (estimated error including systematics). The time-averaged spectrum from T+0.39 to T+310.10 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.74 +- 0.38. The fluence in the 15-150 keV band is 1.0 +- 0.2 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T+5.18 sec in the 15-150 keV band is 0.5 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
