Comparison of spectroscopic and photometric redshifts (z_spec and z_phot) and the normalized redshift deviation (Δz_norm). Left: Comparison between z_spec and z_phot. The solid black line represents the identity line (z_spec = z_phot). Middle: Δz_norm as function of z_spec. Right: Δz_norm as function of z_spec. In the latter two cases, the solid black line corresponds to the constant function where Δz_norm = 0.
