Spectroscopic vs. photometric redshifts for the CLASH spec-z sample showing Le Phare (bottom) and BPZ (top) performances for the spec-z secure redshift in black squares, likely redshift in dark grey diamonds and one emission line redshift in blue hexagons observed in at least 13 filters. We also added galaxies with a number of detections in less than 13 filters in light grey dots. The red crosses mark the spec-z for which the closest HST photometry match had a possible other solution at less than 3′′. The brown dashed, and dotted curves correspond to zp = zs ± 0.02(1 + zs), and zp = zs ± 0.15(1 + zs).
