Pseudo-phase-space density profiles of the stack cluster. Solid lines: Q(r) ≡ ρ/σ³ (top panel) and (bottom panel), as a function of cluster-centric radius r/r₂₀₀, within 1 σ confidence regions (shaded gray regions). The dash-dotted (navy) lines are the theoretical relations Q(r) ∝ r^-1.84 and Q_r(r) ∝ r^-1.92 from Dehnen & McLaughlin (2005), with free normalization fit to the data. The dashed (red) line in the top panel is the theoretical relation Q(r) ∝ r^-2.1 for massive halos at z = 1 from Fig. 6 in Lapi & Cavaliere (2009). The line is almost indistinguishable from the observational relation (solid black line). In both panels, the vertical dashed and dash-dotted (magenta) lines indicate the location of r_-2 and r₂₀₀, respectively.
