In each panel, the fraction of the mass-matched sample of green galaxies, divided according to the transition mass as a function of the environment, is given for the three green sub-classes combined (C4–6) and separately (C4, C5, and C6). The δ-bins correspond to the quartiles of the δ distribution for the whole sample, and the fractions are normalised to the total number of galaxies in the same sub-class, i.e. for each sub-class the fractions in δ bins sum up to 100%. The solid and dashed lines correspond to the weighted fit for low- (9.5 ≲ log(M_star/M_⊙)≲10.6) and high-mass (10.6 ≲ log(M_star/M_⊙)≲11.5) relations, respectively. The shaded stripes around lines display 1σ of the fit. The slope of the fit is given in the legend. The number of galaxies in low- and high-mass samples, respectively for each sub-class, are given in parenthesis.
