Completeness as a function of redshift in four mass bins, for the six final CFC algorithms. The four colors correspond to different mass bins, respectively [10^13.5, 10¹⁴], [10¹⁴, 10^14.5], [10^14.5, 10¹⁵] and [10¹⁵, 10¹⁶] M_⊙. The error bars represent the 68% confidence interval, following the Wilson score interval approach. Each catalog of detections has been trimmed to the most reliable detections insuring a mean purity of 80% in the range M >  10¹⁴ M_⊙ and z_true <  2.
