"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.
