Colour-magnitude diagram (g-i) vs. i for three rich clusters in the CFHTLS W1 field. Empty black circles are candidate cluster galaxies. The underlying distribution is their normalized density. In red are galaxies selected as ETGs at the cluster redshift by LePhare. Smaller black points are galaxies selected as RS members, i.e. lying ± 0.3 from the best fit RS.
