Global properties of LEWIS galaxies as a function of the cluster environment. The PPS diagram shows the relative velocity versus the projected radius for the LEWIS sample (coloured points), and galaxies from Christlein & Zabludoff (2003) catalogue (white circles). LEWIS galaxies are colour-coded according to the stellar mass (top-left panel), metallicity (top-right panel), chemical abundance (lower-left panel), and presence of rotation (lower-right panel). The shaded grey regions indicate different infall stages (Rhee et al. 2017; Forbes et al. 2023): early infall (dark grey) and late infall (light grey).
