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/cm 2 /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. ...
