Completeness of the z_phot sample as a function of the R_C magnitude, separately for red (B − R_C ≥ 1.5, red dots) and blue (B − R_C< 1.5, blue diamonds) galaxies. The dashed line represents the adopted completeness as a function of R_C for the sample of passive members, and, down to R_C = 23, for the sample of SF members also. For R_C> 23, we adopt the same completeness used for brighter SF members.
