TOPz photo-z statistics as a function of the apparent Z-band magnitude. Photo-z accuracy is defined as σ_NMAD (see Sect. 8.2 and Eq. (39)). Outlier fraction is defined using redshift ζ absolute deviation from spectroscopic redshift for two different Δζ thresholds: 0.05 and 0.1. Upper panel: outlier fraction as a function of apparent magnitude. The outlier fractions for two different thresholds are marked in green and orange colours. The coloured dashed lines show the outlier fractions over the whole galaxy sample. Lower panel: photo-z accuracy distribution widths as described by the σ_NMAD value. The dashed line shows the σ_NMAD value calculated over the whole galaxy set.
