Notes. Reduced χ2 for the fit of a Gaussian function to the flux distribution (Col. 2); lognormal distribution to the flux distribution (Col. 3); a constant line to the excess variance vs. flux (Col. 4) and a linear function (Col. 5) for the excess variance vs. flux in the various wavebands. Columns 6 and 7 give the Pearsons r and Spearmans ρ correlation coefficients, respectively. The values in the brackets denote the null hypothesis probabilities.
