TITLE: GCN CIRCULAR NUMBER: 13404 SUBJECT: GRB 120701A: Swift-BAT refined analysis DATE: 12/07/03 03:41:43 GMT FROM: Scott Barthelmy at NASA/GSFC 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), D. M. Palmer (LANL), T. Sakamoto (GSFC/UMBC), E. Sonbas (GSFC), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (GWU) (i.e. the Swift-BAT team): Using the data set from T-61 to T+242 sec from recent telemetry downlinks, we report analysis of BAT GRB 120701A (trigger #525477). There was no initial set of GCN Notices nor a rapid-response circular because of the power outage at GSFC when this burst occurred. The BAT ground-calculated position is RA, Dec = 80.338, -58.531 deg which is RA(J2000) = 05h 21m 21.0s Dec(J2000) = -58d 31' 52.3" with an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment). The partial coding was 60%. The mask-weighted light curve shows several overlapping peaks starting at ~T-2 sec and ending at ~T-20 sec. T90 (15-350 keV) is 13.8 +- 0.7 sec (estimated error including systematics). The time-averaged spectrum from T-0.0 to T+15.4 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.05 +- 0.10. The fluence in the 15-150 keV band is 1.4 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+10.36 sec in the 15-150 keV band is 1.6 +- 0.2 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/525477/BA/ [GCN OPS NOTE(03jul12): Per author's request: "It should be noted that the trigger_time for trigger 525477 is 07:50:41.57 UT on 01 July 2012."]
