Morphology classification using (u − r)0 rest-frame colour and Sérsic index in the r-band. The vertical line indicates nr = 2.5, and the horizontal line indicates (u − r)0 = 2.3. This classification was proposed by Vika et al. (2015). The blue dots represent galaxies in CGs, while the orange dots represent galaxies in the control sample.
