Relations between β(r) and the logarithmic derivative of the total mass density profile, γ(r), for all, passive, and SF member galaxies (top, middle, and bottom panel, respectively), within 1σ confidence regions (shaded regions), and the theoretical γ − β relation of Hansen & Moore (2006) (dashed line). The vertical lines indicate the location of r_-2 (dashed) and r₂₀₀ (dash-dotted).
