Normalized skewness S₄ as a function of the B absolute luminosity (upper panels) and stellar mass (lower panels). The limits of the subsamples in absolute magnitude and stellar mass are shown in the left upper and lower panels (symbols and colours are the same as in Fig. 4). We note that black points corresponding to galaxies with M< −19.50 or M_∗ ≥ 9.0 M_⊙ are only plotted for the first redshift bin ([0.5, 0.7]), but most of them are not visible as they lie below the points of the other samples. The dashed line corresponds to S₄ = 8. In the top panels, the dotted line is the prediction from second-order perturbation theory for the matter distribution in real space; the solid line is the prediction of S₄ for galaxies with M_B(z = 1.1) − 5log (h) ≤ −20.5 (to be compared to blue pentagons): it was obtained from the matter values, converted to redshift space and divided by the corresponding linear bias factor.
