Completeness as a function of mass and redshift for the six final CFC algorithms. The black lines corresponds to completenesses of 50, 80 and 90%. The pixel size corresponds to about Δlog(M/M_⊙) = 0.08 and Δz = 0.05, but the image was smoothed with a Gaussian kernel to a resolution of 0.20 log(M/M_⊙) × 0.25 (FWHM) for display purposes. The mask is applied where the number of clusters per pixel is zero before smoothing. Each catalog of detections has been trimmed to the most reliable detections, ensuring a mean purity of 80% in the range M >  10¹⁴ M_⊙ and z_true <  2.
