Table 7: a) Parameters of the linear fits $I'=a+b\;\log \sigma$. First column: y-intersect of the fit and its error; second column: slope, and corresponding error, of the linear fit; $\alpha $: probability, given by a non-parametric Spearman test, that the slope of the fit is significatively different from zero by chance; N: number of galaxies used to make the fit; t: t parameter to test the hypothesis b=0 (a t value higher than 1.9 indicates that the slope is significant different from zero with a significance level lower than 0.05); $\sigma _{\rm std}$: standard deviation about the fit; $\sigma_{\exp}$: standard deviation expected from the errors; $\sigma _{\rm res}$: standard deviation not explained from the errors.
