Comparison of our photometric redshifts with the VVDS, VIPERS, PRIMUS, and BOSS most secure spectroscopic redshifts, for galaxies with K ≤ 22 (top panels) and NUV ≤ 25 (bottom panels). We report the dispersion (σ_NMAD) by combining all the surveys, while the catastrophic fractions (f_cat defined as | Δz | /(1 + z_s) > 0.15) are given for all surveys but PRIMUS (black value), which is shown separately (gray value). The observed distributions of photometric errors are compared to a Gaussian distribution with the same σ (right panels).
