Using the data set from T-239 to T+963 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 190322***A*** (trigger #894268)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 314.725, 41.840 deg which is 
   RA(J2000)  =  20h 58m 54.0s 
   Dec(J2000) = +41d 50' 24.5" 
with an uncertainty of 3.5 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 91%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 664.00 +- 0.00 sec (estimated error including systematics).
 
The time-averaged spectrum from T+0.00 to T+664.00 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
2.23 +- 0.31.  The fluence in the 15-150 keV band is 1.5 +- 0.3 x 10^-06 erg/cm2.
The 1-sec peak photon flux measured from T+0.00 sec in the 15-150 keV band
is 0.0 +- 0.0 ph/cm2/sec.  All the quoted errors are at the 90% confidence
level.

## Special note (please do not include this in the email circular):
## Becuase E0 = 2.28333 is outside of the BAT energy range (15-350 keV),
## A simple power-law model is chosen despite delta chi2 > 6.
