Normalised median absolute deviation of the photo-z error (σ_NMAD; top panel) and outlier rate (η; bottom panel) in bins of r-band magnitude for the spectroscopic subsamples of miniJPAS (black squares) and J-NEP (red circles). Symbols linked by solid lines represent measurements including all sources within a 0.5 mag interval in r-band magnitude, while the ones linked by dotted lines indicate the values obtained considering only the 50% of sources with higher odds in each magnitude bin. Error bars indicating the 16–84th percentile confidence intervals were obtained with bootstrap resampling in the case of σ_NMAD and the Wilson formula for binomial distributions in the case of η.
