Ratio between the number of star-forming (SFR > 0.02 M_⊙ yr⁻¹) and quiescent galaxies as a function of clustercentric distance r. Low-mass galaxies (10.15 < log M_*(M_⊙) < 11) are shown on the left and massive galaxies (log M_*(M_⊙) > 11) on the right. Results are shown at low redshift (upper panels) and high redshift (lower panels). For r > 2 R₅₀₀ we separately plot the profiles of the overlapping and isolated regions (r_ov = 6 R₅₀₀, see Sect. 3). On the right panels, the dotted line represents the massive overlapping populations without the BCGs of the neighbouring clusters, central BCGs are excluded in all plots. The coloured bands represent the 68 % confidence intervals obtained with Poisson statistics (see Sect. 3).
