Probability density function of the number of neighbours within a projected distance of 0.1 Mpc (top), the distance to the cluster core (centre), and the local galaxy density (bottom) for all the morphological types: ET (red), LT (dark blue), blue ET with recent SF (violet), blue ET LCBGs (green), and the rest of blue ETs (yellow). These curves are estimated by applying a Gaussian kernel density estimator to smooth the distribution.
