"Non-triggered BATSE Gamma Ray Bursts. Extended and revised logN-logS."
We present preliminary results of an off-line search for non-triggered
gamma-ray bursts (GRBs) in the
BATSE daily records for about 7 years of observations.
We found more GRB-like events than the yield of the similar search of
Kommers et al.
and extended the LogN-logP distribution down to
~0.1 ph/cm2/s.
The indication of a turnover of the logN-logP at a small P
is not confirmed: the distribution is straight at 1.5 decades
and cannot be fitted with a standard candle cosmological model.
