TITLE: GCN CIRCULAR NUMBER: 16573 SUBJECT: GRB 140710A: Swift-BAT refined analysis DATE: 14/07/10 21:46:28 GMT FROM: Hans Krimm at NASA-GSFC T. Sakamoto (AGU), 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), D. M. Palmer (LANL), M. H. Siegel (PSU), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (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 140710 (trigger #603954) (Siegel, et al., GCN Circ. 16563). The BAT ground-calculated position is RA, Dec = 41.088, 35.499 deg which is RA(J2000) = 02h 44m 21.0s Dec(J2000) = +35d 29' 54.8" with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 58%. The mask-weighted light curve shows a single peak of duration ~4 seconds, starting at T0. T90 (15-350 keV) is 3.52 +- 0.91 sec (estimated error including systematics). The time-averaged spectrum from T-0.23 to T+3.80 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 2.00 +- 0.23. The fluence in the 15-150 keV band is 2.3 +- 0.3 x 10^-07 erg/cm2. The 1-sec peak photon flux measured from T+0.04 sec in the 15-150 keV band is 1.9 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level. The results of the batgrbproduct analysis are available at http://gcn.gsfc.nasa.gov/notices_s/603954/BA/
