Marginal distributions of the logarithmic slopes of the linear (l ≥ 0.9) Q profiles, for different morphological classes (E, S0, S in the top, middle, and bottom panel, respectively) using different models (color coded as in Table 1), for sigv scaling. Left panels: Q_ρ; right panels: Q_ν. Grey (respectively yellow) shadings indicate the simulation-based prediction for the slope of DM tracers (respectively subhalos), −1.84 ± 0.025 (respectively −1.29 ± 0.03).
