Using the data set from T-240 to T+302 sec from recent telemetry
downlinks, we report further analysis of BAT GRB 100514A (trigger
#421962) (Markwardt, et al., GCN Circ. 10759). The BAT ground-calculated
position is RA, Dec = 328.757, 29.175 deg, which is
RA(J2000) = 21h 55m 01.7s
Dec(J2000) = +29d 10' 29.8"
with an uncertainty of 2.5 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 76%.
The mask-weighted light curve shows FRED-like peak starting at ~T-2 sec,
peaking at ~T+7 sec, and ending at ~T+38 sec. T90 (15-350 keV) is 26.2
+- 8.2 sec (estimated error including systematics).
The time-averaged spectrum from T+0.3 to T+30.8 sec is best fit by a
simple power-law model. The power law index of the time-averaged
spectrum is 1.97 +- 0.25. The fluence in the 15-150 keV band is 4.0 +-
0.7 x 10-7 erg/cm2. The 1-sec peak photon flux measured from T+6.23 sec
in the 15-150 keV band is 0.6 +- 0.2 ph/cm2/sec. All the quoted errors
are at the 90% confidence level.
