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
