TITLE: GCN CIRCULAR NUMBER: 12939 SUBJECT: GRB 120212A: Swift-BAT refined analysis DATE: 12/02/12 16:14:22 GMT FROM: Scott Barthelmy at NASA/GSFC S. D. Barthelmy (GSFC), W. H.

Sato (ISAS), E. Sonbas (NASA/GSFC/Adiyaman U), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from recent telemetry downlinks, we report further analysis of BAT GRB 120212A (trigger #514709) (Sonbas, et al., GCN Circ. 12930). The BAT ground-calculated position is RA, Dec = 43.086, -18.043 deg, which is RA(J2000) = 02h 52m 20.6s Dec(J2000) = -18d 02' 33.0" with an uncertainty of 1.6 arcmin, (radius, sys+stat, 90% containment). The partial coding was 22%. The mask-weighted light curve shows a single FRED pulse starting at ~T-0.7. peaking at ~T+1, and ending at ~T+6 sec. T90 (15-350 keV) is 5.52 +- 1.04 sec (estimated error including systematics). The time-averaged spectrum from T-0.76 to T+6.09 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 2.05 +- 0.19. The fluence in the 15-150 keV band is 5.1 +- 0.6 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.02 sec in the 15-150 keV band is 2.1 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
