YOLO–CL (continuous lines) and redMaPPer (dashed lines) cluster detection completeness above a given X-Ray luminosity, L_XL_X (left panel), M₅₀₀ (middle panel), and R₅₀₀ (right panel). YOLO–CL recovers all clusters at L_X ≳ 1–3 × 10⁴⁴ erg s⁻¹, M₅₀₀ ≳ 2–3 × 10¹⁴M_⊙,R₅₀₀ ≳ 0.75–0.8 Mpc and z ≳ 0.4. At lower luminosity, mass, radius and redshift, its performance worsens. The redMaPPer algorithm recovers all clusters at L_X ≳ 30–90 × 10⁴⁴ erg s⁻¹, M₅₀₀ ≳2–6× 10¹⁴M_⊙, R₅₀₀ ≳ 0.8–1.2 Mpc and z ≳ 0.4. At high redshifts both YOLO–CL and redMaPPer demonstrate a similar performance that is limited by the SDSS depth.
