Completeness as a function of Y_5R500 for a cluster with effective spherical θ₅₀₀ = 5.63′. Left: Completeness for different orientations of a cluster with q₁ = 0.6, q₂ = 0.8. Middle: Completeness for a cluster with different triaxialities, but with the major axis oriented along the LOS, with cos θ = 1.0, ϕ = 0°. Right: Completeness for a cluster with different triaxialities, but with the major axis oriented on the plane of sky (POS), with cos θ = 0.0, ϕ = 90°.
