Using the data set from T-239 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 180314***A*** (trigger #814129)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 99.173, -24.495 deg which is 
   RA(J2000)  =  06h 36m 41.6s 
   Dec(J2000) = -24d 29' 41.0" 
with an uncertainty of 4.0 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 24%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 50.5 +- 21.8 sec (estimated error including systematics).
 
The time-averaged spectrum from T-11.8 to T+109.8 sec is best fit by a power law
with an exponential cutoff.  This fit gives a photon index 0.84 +- 0.25, 
and Epeak of 94.2 +- 17.6 keV (chi squared 49.42 for 56 d.o.f.).  For this
model the total fluence in the 15-150 keV band is 1.1 +- 0.0 x 10^-05 erg/cm2
and the 1-sec peak flux measured from T+3.05 sec in the 15-150 keV band is
7.9 +- 0.6 ph/cm2/sec.  A fit to a simple power law gives a photon index
of 1.51 +- 0.05 (chi squared 74.31 for 57 d.o.f.).  All the quoted errors
are at the 90% confidence level.
