Further analysis of Swift-BAT GRB050117a (Sakamoto et al., GCN Circ 2952)
yields the fluence to be 7x10^-6 erg/cm2 in the 15-350 keV band and a
peak flux of 0.88 +/- 0.06 ph/cm2/sec (also 15-350 keV) in a 5-sec wide
window bracketing the highest peak (starting at T+85 sec) in the multi-peak
lightcurve. We note that the ~200-sec duration quoted in Circ 2952
was an eye-ball fit for the the total duration. The proper T90 time
is 169 sec (15-350 keV).
