Distribution fits: the observed flux distribution is fitted with a lognormal PDF. The blue line shows the disfavored single lognormal distribution, the red region line indicates the excess flux density compared to the best-fit distribution. We chose the bin number according to Scott’s rule and we chose a logarithmic binning. The error bars are computed from Poisson statistics and a block boot strap: see Sect. 2 for details.
