Correlation matrixes showing Spearman’s rank coefficients between the inspected physical (luminosity, half-light radius, global average metallicity, velocity dispersion) and orbital parameters (pericentre, apocentre, eccentricity, time since the last pericentric passage) in the case of a low (left panel) and high (right panel) mass MW potential. In both cases, the upper right part corresponds to values for the on-plane sample, while the lower left part is for the off-plane sample; orange and blue shades correspond to the numerical values shown, with darker shades corresponding to a stronger correlation.
