Using the data set from T-239 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 140729***A*** (trigger #607399)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 272.168, -20.432 deg which is 
   RA(J2000)  =  18h 08m 40.4s 
   Dec(J2000) = -20d 25' 56.1" 
with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 95%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 0.16 +- 0.04 sec (estimated error including systematics).
 
The time-averaged spectrum from T-0.08 to T+0.15 sec fit by a simple
power-law model shows the power law index of 2.57 +- 0.11 (chi squared 62.65 for 57 d.o.f.).
The fluence in the 15-150 keV band is 9.7 +- 0.6 x 10^-08 erg/cm2.
The 1-sec peak photon flux measured from T-0.46 sec in the 15-150 keV band
is 2.0 +- 0.2 ph/cm2/sec.
 
A single blackbody fit to the time-averaged spectrum shows the blackbody
temperature of 8.72 +- 0.58 keV (chi squared 78.21 for 57 d.o.f.).
A thermal bremsstrahlung model fit shows the temperature of 36.26 +- 4.73 keV
(chi squared 42.44 for 57 d.o.f.).  A double blackbody fit shows the lower temperature
of 4.20 +1.09 keV and the higher temperature of 11.88 (error not unconstrained) keV
(chi squared 42.20 for 55 d.o.f.).  All the quoted errors are at the 90% confidence level.
