Structural parameters of Hydra’s dwarf galaxies as a function of their projected clustercentric distance. Panel rows from top to bottom show: g − r color, effective radius R_e, mean effective surface brightness , and the Sérsic index n. Each column corresponds to a different luminosity bin. Linear trend lines are shown in each panel, for both dwarf populations. Red dots and dashed lines are used for red dwarfs, while blue triangles and dash-dotted lines represent the blue dwarf population. The ρ parameter in each panel expresses Spearman’s rank correlation coefficient for the correlation between the parameter and the distance from the cluster center (black indicates the whole dwarf sample, red only the red dwarfs).
