Residuals of the median photometric redshift relative to the spectroscopic redshift for 25 416 galaxies in the EDF-F field (left) and 36 564 galaxies in the EDF-N (right). The spectroscopic information comes from a compilation of publicly available external spectroscopic surveys, starting from a redshift of z_s = 0.05 in the two figures. The red lines indicate the associated bias and scatter, estimated in redshift bins containing at least 200 galaxies.
