Differences between photo-ɀ point-estimates produced by BPZ in PHOTOPIPE computed without the second pass i-band (‘9-band’) and with the second pass i-band (‘10-band’), using a full simulated KiDS wide-field sample described in van den Busch et al. (2020). Metrics here are not directly comparable to Fig. 25 due to this sample being simulated, having a different redshift baseline, and representing a full wide-field sample (unmatched to spectroscopy). Therefore, only relative differences between the nine- and ten-band cases are relevant. Metrics are computed as in Fig. 25, except metrics here are shown as percentage difference with respect to the nine-band case.
