Colour versus stellar mass diagram distribution of galaxies in relaxed in the left panel and disturbed in the middle one, for the low-redshift (top) and high-redshift (bottom) bins. In the left and middle panels we show the satellite galaxy densities distribution for the disturbed and relaxed clusters; whereas in the right panels, we have the difference in the galaxy density between relaxed and disturbed galaxy clusters after normalising. Notice that the sum of the densities in the last panel equals zero. There is an excess of galaxies in the red sequence of the diagram in relaxed clusters compared with the disturbed ones.
