TITLE: GCN CIRCULAR NUMBER: 10761 SUBJECT: GRB 100514A: Swift-BAT refined analysis DATE: 10/05/15 01:48:18 GMT FROM: Craig Markwardt at NASA/GSFC/UMD S. D. Barthelmy (GSFC), W. H. Baumgartner (GSFC/UMBC), J. R. Cummings (GSFC/UMBC), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), C. B. Markwardt (GSFC/UMD), D. M. Palmer (LANL), T. Sakamoto (GSFC/UMBC), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC), T. N. Ukwatta (GWU) (i.e. the Swift-BAT team): Using the data set from T-240 to T+302 sec from recent telemetry downlinks, we report further analysis of BAT GRB 100514A (trigger #421962) (Markwardt, et al., GCN Circ. 10759). The BAT ground-calculated position is RA, Dec = 328.757, 29.175 deg, which is RA(J2000) = 21h 55m 01.7s Dec(J2000) = +29d 10' 29.8" with an uncertainty of 2.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 76%. The mask-weighted light curve shows FRED-like peak starting at ~T-2 sec, peaking at ~T+7 sec, and ending at ~T+38 sec. T90 (15-350 keV) is 26.2 +- 8.2 sec (estimated error including systematics). The time-averaged spectrum from T+0.3 to T+30.8 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.97 +- 0.25. The fluence in the 15-150 keV band is 4.0 +- 0.7 x 10-7 erg/cm2. The 1-sec peak photon flux measured from T+6.23 sec in the 15-150 keV band is 0.6 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
