Gini coefficients derived for the radial profiles obtained from the CO distributions in the galaxies of the sample as a function of L_X (upper panel) and the concentration index of cold molecular gas (middle panel). Flux-weighted mean radii of the normalized distribution of cold molecular gas as a function of the Gini coefficients of the radial profiles derived for the galaxies of our sample (lower panel). Error bars account for the estimated uncertainties on the Gini coefficients. We indicate the estimated correlation coefficients (R_s) and their associated p-values for the three distributions. Gini coefficient values are color-coded as a function of L_X (black indicates nonAGN galaxies).
