Robust scatter (σ_NMAD; upper panels) and OLF (lower panels) for the consensus photo-z estimates (z_1,median) as a functionof 4.5 μm magnitude. Shaded regions illustrate the statistical uncertainties on the respective metrics derived from bootstrap resampling. The magnitude range plotted for each field is representative of the magnitude distribution of the spectroscopic sample and is not indicative of the relative photometric depths (see Fig. 1).
