Using the data set from T-239 to T+963 sec from recent telemetry downlinks,
we report further analysis of BAT GRB 100614A (trigger #424716)
(Stratta, et al., GCN Circ. 10837).  The BAT ground-calculated position is
RA, Dec = 263.534, 49.232 deg which is 
   RA(J2000)  =  17h 34m 08.2s 
   Dec(J2000) = +49d 13' 56.4" 
with an uncertainty of 1.6 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 56%.
 
The mask-weighted light curve shows a relatively smooth peak starting
at ~T-10 sec, peaking around T+50 sec, and ending at ~T+275 sec.
T90 (15-350 keV) is 225 +- 55 sec (estimated error including systematics).
 
The time-averaged spectrum from T-9.0 to T+282.0 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
1.88 +- 0.15.  The fluence in the 15-150 keV band is 2.7 +- 0.2 x 10^-6 erg/cm2.
The 1-sec peak photon flux measured from T+31.00 sec in the 15-150 keV band
is 0.7 +- 0.2 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.
