Using the data set from T-240 to T+962 sec from the recent telemetry downlink,
we report further analysis of BAT GRB 201006***A*** (trigger #998907)
(NAME, et al., GCN Circ. xxxx).  The BAT ground-calculated position is
RA, Dec = 61.910, 65.148 deg which is 
   RA(J2000)  =  04h 07m 38.5s 
   Dec(J2000) = +65d 08' 53.6" 
with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 33%.
 
[Description about the mask-weighted light curve]
T90 (15-350 keV) is 0.5 +- 0.1 sec (estimated error including systematics).
 
The time-averaged spectrum from T-0.0 to T+0.5 sec is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
1.42 +- 0.24.  The fluence in the 15-150 keV band is 1.3 +- 0.2 x 10^-07 erg/cm2.
The 1-sec peak photon flux measured from T-0.23 sec in the 15-150 keV band
is 2.1 +- 0.3 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.
