Dependence of z ∼ 0.84 galaxy sizes (top), Sérsic indices (middle), and the bulge-to-total ratio (bottom) on the stellar mass (left) and the environment (right) for the global sample. In each panel, we show the Spearman correlation coefficient, ρ, and the corresponding probability of an uncorrelated dataset having the same distribution in parentheses (the coefficient is computed for galaxies with M_⋆ >  10¹⁰ M_⊙).
