(i.e. the Swift-BAT team):
 
Using the data set from T-426 to T+962 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 140516***A*** (trigger #599188)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 252.976, 39.961 deg which is 
   RA(J2000)  =  16h 51m 54.1s 
   Dec(J2000) = +39d 57' 39.6" 
with an uncertainty of 2.6 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 75%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 0.3 +- 0.1 sec (estimated error including systematics).
 
The time-averaged spectrum from T-0.0 to T+0.3 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
1.89 +- 0.32.  The fluence in the 15-150 keV band is 3.0 +- 0.7 x 10^-08 erg/cm2.
The 1-sec peak photon flux measured from T-0.33 sec in the 15-150 keV band
is 0.5 +- 0.1 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.

## Special note (please do not include this in the email circular):
## Because this is a particularly short burst (T90 < 1 sec), only the simple power-law fit
## and special SGR fit (if the burst is within 2 deg of the Galactic plane) are considered.
## That is, the cutoff power-law fit is not one of the options despite the low chi2 value.
