Using the data set from T-315 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 151205***A*** (trigger #666352)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 229.288, 35.768 deg which is 
   RA(J2000)  =  15h 17m 09.1s 
   Dec(J2000) = +35d 46' 04.5" 
with an uncertainty of 1.4 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 93%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 64.0 +- 35.8 sec (estimated error including systematics).
 
The time-averaged spectrum from T-11.4 to T+68.6 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
1.10 +- 0.13.  The fluence in the 15-150 keV band is 1.4 +- 0.1 x 10^-06 erg/cm2.
The 1-sec peak photon flux measured from T+12.05 sec in the 15-150 keV band
is 0.4 +- 0.1 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.
