We present preliminary results of an off-line search for non-triggered
gamma-ray bursts (GRBs) in the
BATSE daily records for about 5.7 years of observations.
We found more GRB-like events than the yield of the similar search of
Kommers et al. (1998) and extended the distribution
down to
.
The indication of a turnover of the
at a small P
is not confirmed: the distribution is straight at 1.5 decades
with the power law index -.6
and cannot be fitted with a standard candle cosmological model.
Key words: gamma-ray bursts / methods: data analysis
