TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3119 SUBJECT: GRB 050319: Swift-BAT refined analysis DATE: 05/03/19 16:18:59 GMT FROM: Hans Krimm at NASA-GSFC H. Krimm (GSFC/USRA), T. Sakamoto (GSFC/NRC), S. Barthelmy, L. Barbier (GSFC), J. Cummings (GSFC/NRC), E. Fenimore (LANL), N. Gehrels (GSFC), D. Hullinger (GSFC/UMD), C. Markwardt (GSFC/UMD), F. Marshall (GSFC), J. Nousek (PSU), D. Palmer (LANL), A. Parsons (GSFC), G. Sato (ISAS), M. Still (GSFC/USRA), M. Suzuki (Saitama), J. Tueller (GSFC) on behalf of the Swift-BAT team: Analysis of the full data set for the Swift-BAT GRB 050319 (Krimm, et al., GCN 3117) yields a fluence of 8 X 10^-7 erg/cm2 in the 15-350 keV band and a peak flux of 1.7 ph/cm2/sec (also 15-350 keV). The photon index of the 1-s peak spectrum ( starting at T0 +0.36 sec.) is 2.1 +- 0.3 (90% confidence). The time-averaged spectrum yields a photon index of 2.2 +- 0.2. The overall measures of burst duration give T90 = 10 +- 2 seconds (including systematics).
