Using the data set from T-239 to T+963 sec from the recent telemetry
we report further analysis of BAT GRB 230414B (trigger #1164180)
(D'Ai et al., GCN 33612). The BAT ground-calculated position is
RA, Dec = 181.052, 53.179 deg which is
RA(J2000) = 12h 04m 12.5s
Dec(J2000) = +53d 10' 44.7"
with an uncertainty of 2.4 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 80%.
The mask weighted light curve shows a single main fast rise exponential
decay type pulse.
T90 (15-350 keV) is 25.98 +- 8.86 sec (estimated error including
The time-averaged spectrum from T-1.77 to T+27.14 sec is best fit by a
power-law model. The power law index of the time-averaged spectrum is
1.60 +- 0.30. The fluence in the 15-150 keV band is 4.7 +- 1.0 x 10^-07
The 1-sec peak photon flux measured from T+9.31 sec in the 15-150 keV band
is 0.6 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence
