We have re-analyzed GRB 051105 (GCN Circ 4188, Mineo et al., and
GCN Circ 4190, Cummings et al.) based on new time interval T0
to T0 + 0.120 sec.
The improved refined BAT ground position is (RA,Dec) = 265.277, 34.949,
{17h 41m 6.6s, 34d 56' 56.8"} [deg; J2000] +- 2.5 arcmin,
(90% containment). The partial coding was 81%.
The photon index of the time-averaged spectrum is 1.33 +- 0.35
in the time interval TO + 0.122 sec. The fluence in the 15-150 keV
band is (2.0 +- 0.46) x 10^-8 erg/cm2. The peak photon flux in the
same time window measured in the 15-150 band is (2.0 +- 0.43)
ph/cm2/sec. All the quoted errors are at the 90% confidence level.
