Colour-density diagram (top panel) of the ETGs inside the virial radius of the Fornax cluster as a function of the cluster density Σ. The cluster density as a function of the projected distance from the cluster centre in megaparsec is shown in the lower panel. This is derived in circular annuli with bin of 0.2° (out to 2°), accounting for all cluster members given by Ferguson (1989).
