Dependence of non-parametric tracers (from top to bottom: light concentration, asymmetry, Gini, and moment of light) on the environment for three different stellar mass bins (from left to right). We add to all panels the relation for the global sample at M_⋆ >  10¹⁰ M_⊙ as empty grey squares. In each panel, we show the Spearman correlation coefficient, ρ, and the corresponding probability of an uncorrelated dataset having the same distribution in parentheses. Overall we find that both stellar mass and environment have some impact on non-parametric morphology, with stellar mass having the strongest impact on the median of the population (as measured by the average gradient).
