TITLE: GCN CIRCULAR NUMBER: 35322 SUBJECT: GRB 231210B: Swift-BAT refined analysis DATE: 23/12/11 21:10:59 GMT FROM: Mike Moss at NASA GSFC <mikejmoss3@gmail.com> T. Sakamoto (AGU), S. D. Barthelmy (GSFC), H. A. Krimm (NSF), S. Laha (GSFC/UMBC), A. Y. Lien (U Tampa), C. B. Markwardt (GSFC), D. M. Palmer (LANL), K. L. Page (U Leicester) T. Parsotan (GSFC/UMBC), M. Stamatikos (OSU) (i.e. the Swift-BAT team): Using the data set from T-36 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 231210B (trigger #1201696) (Page, et al., GCN Circ. 35314). The BAT ground-calculated position is RA, Dec = 95.803, -48.335 deg which is RA(J2000) = 06h 23m 12.7s Dec(J2000) = -48d 20' 04.6" with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 17%. The mask-weighted light curve shows a FRED pulse potentially followed by a dimmer spike. T90 (15-350 keV) is 7.47 +- 0.65 sec (estimated error including systematics). The time-averaged spectrum from T-0.23 to T+7.82 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.08 +- 0.19. The fluence in the 15-150 keV band is 1.4 +- 0.2 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T-0.24 sec in the 15-150 keV band is 3.9 +- 0.7 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
