TITLE: GCN CIRCULAR NUMBER: 14146 SUBJECT: GRB 130122A: Swift-BAT refined analysis DATE: 13/01/24 00:58:49 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), W. H.

Parsons (GSFC), T. Sakamoto (GSFC/UMBC), G. Sato (ISAS), 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 further analysis of BAT GRB 130122A (trigger #546731) (Lien, et al., GCN Circ. 14140). The BAT ground-calculated position is RA, Dec = 194.307, 59.003 deg, which is RA(J2000) = 12h 57m 13.8s Dec(J2000) = +59d 00' 09.2" with an uncertainty of 3.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 89%. The mask-weighted light curve shows a single roughly FRED-like peak starting at ~T+0 sec, peaking at ~T+10 sec, and ending at ~T+100 sec. T90 (15-350 keV) is 64 +- 36 sec (estimated error including systematics). The time-averaged spectrum from T-12.6 to T+67.4 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.34 +- 0.24. The fluence in the 15-150 keV band is 7.4 +- 1.1 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T+10.92 sec in the 15-150 keV band is 0.4 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
