Comparison of the σ₆₈ values (top row) and outlier fractions (bottom row) for the W1 and G09 samples obtained using the DEEPz and BCNz2 methods. Columns (1) and (2) correspond to the implementation of the model trained with the W1 sample with missing NB values inferred. Columns (3) and (4) correspond to the implementation of the model trained with the G09+COSMOS sample with missing NB flues inferred. Upper panels (a) and (b): σ₆₈ for DEEPz and BCNz2 plotted against i-band magnitude for (a) and against redshift for (b). Lower panels (c) and (d): Fraction of outliers with Δz >  0.02 plotted as a function of i-band magnitude for (c) and redshift for (d).
