Left panel: arithmetic mean of Q for all mock galaxies with max[g_obs]≤0.01a₀ as a function of radial range in units of r_d. Black and blue lines represent MI and MG, respectively, with v_∞ ≃ v_flat = v_tot(500 kpc). Cyan and brown lines represent MI and MG, respectively, with v_∞ ≃ v_flat = v_tot(r_cut), where r_cut denotes the radii at which the integrals are cut. The inset is a magnification of N_range = [0, 10]. Right panel: ΔQ^MI − ΔQ^MG as a function of radial range. The error bars are smaller than the points.
