Top:z_mean photometric redshift distributions obtained with DNF for the six photometric samples up to m_VIS = 25. The z_mean photo-z estimate returned by DNF is the value resulting from the mean of the nearest neighbors redshifts. Lower: photometric redshift distributions obtained with DNF for the z_mc statistic, which for each galaxy is a one-point sampling of the redshift probability distribution estimated from the nearest neighbor (see text for details). All samples have the same number density of 41.5 galaxies per arcmin².
