TITLE: GCN CIRCULAR NUMBER: 16584 SUBJECT: GRB 140713A: Swift-BAT refined analysis DATE: 14/07/13 23:17:37 GMT FROM: Scott Barthelmy at NASA/GSFC M. Stamatikos (OSU), S. D. Barthelmy (GSFC), W. H. Baumgartner (GSFC/UMBC), J. R. Cummings (GSFC/UMBC), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (NASA/UMBC), C. B. Markwardt (GSFC), V. Mangano (PSU), D. M. Palmer (LANL), T. Sakamoto (AGU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-239 to T+325 sec from recent telemetry downlinks, we report further analysis of BAT GRB 140713A (trigger #604232) (Mangano, et al., GCN Circ. 16581). The BAT ground-calculated position is RA, Dec = 281.141, 59.623 deg which is RA(J2000) = 18h 44m 33.9s Dec(J2000) = +59d 37' 22.3" with an uncertainty of 1.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 97%. The mask-weighted light curve shows two peaks starting at ~T-0.2 sec, peaking at ~T+0.2 and ~T+5 sec, and ending at ~T+10 sec. T90 (15-350 keV) is 5.30 +- 0.66 sec (estimated error including systematics). The time-averaged spectrum from T-0.11 to T+6.68 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.84 +- 0.14. The fluence in the 15-150 keV band is 3.7 +- 0.3 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.11 sec in the 15-150 keV band is 1.9 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
