Photometric versus spectroscopic redshifts and redshift accuracy versus spectroscopic redshift for a sample of 84 galaxies (red stars) for which the photometric redshift was calculated by Małek et al. (2014) using the CIGALE tool. Blue squares correspond to the Abell S0463 cluster. The region of CEs, defined as | z_spec−z_photo | /(1 + z_spec) > 0.15 (Ilbert et al. 2006), is marked by a solid black line. The navy dashed-dotted line corresponds to the z_phot = z_spec. Shadowed areas represent the redshift range rejected from our analysis.
