Photometric redshift vs. r-band magnitude space. Red crosses represent lenses found by the KiDS collaboration, with error bars indicating the range between the predicted maximal and minimal estimated redshift given by the BPZ code. Histograms of redshift and magnitude, for both populations, are plotted along each axis to better visualize the distribution of values. Values of the median magnitude and redshift for both samples are represented by dashed lines (TEGLIE), and solid lines (KiDS) and reported in the plot.
