YOLO-CL DC2 detection completeness and the number of halos as a function of redshift and richness or halo mass. Left: YOLO-CL DC2 detection completeness as a function of redshift and richness (top) or halo mass (bottom). Right: Number of halos as a function of redshift and richness (top) or halo mass (bottom). The vertical colored bars show the color scale for the completeness (left) and the number of halos (right). The YOLO-CL selection is almost flat as a function of redshift up to z ∼ 0.8 when we consider the halo mass. The catalog is ∼100% complete for M_200c ≳ 10^14.6 M_⊙ and richness ≳100 at all redshifts. When characterizing halos by their richness, the completeness is less flat as a function of redshift, as is also shown for SDSS observations in Grishin et al. (2023), and the completeness decreases abruptly to ∼70 − 75% at z > 0.8 and M_200c ≲ 10¹⁴ M_⊙. Comparing the figures on the left and on the right, some bins show very low completeness on the left only because there are no clusters in those bins.
