Robust scatter (σ_NMAD; top) and OLF (bottom) for the consensus photo-z estimate as a function of spectroscopic redshift and 150 MHz radio continuum luminosity in the Boötes field. Top and side panels: trends averaged over all redshifts and luminosities, respectively. For a cell to be plotted we require a minimum offive galaxies - for some redshifts (or luminosities) we only have the number statistics available to plot the statistics averaged over all luminosities (or redshift).
