Top panel: quenched fraction in the function of the 3D radius from the cluster's centre. In solid lines, the quenched fraction of galaxies that inhabit the low-redshift clusters (z<0.5), and in dotted lines, the fraction of quenched galaxies for clusters in high-redshift bins (z≥0.5). Quenched fractions of galaxies in relaxed clusters are presented in blue, and galaxies inside disturbed clusters are presented in red. The shadow areas are the Poisson's noise. Bottom panel: relaxed quenched fraction excess for the high-redshift bin with a solid line and for the high-redshift bin with a dotted line.
