Outlier fraction (top row) as a function of LS10 i-band magnitude (left) and LS10 i-band S/N (right), comparing the original photo-z from XMM-SERVS to the photo-z computed with PICZL. The XMM-SERVS photo-z results are shown both with and without the inclusion of sources for which XMM-SERVS photo-z failed (photo-z = −99). The shaded regions represent the range of XMM-SERVS outlier fractions across the ELAIS-S1, W-CDF-S, and LSS fields. The bottom row panels depict the range of XMM-SERVS variance in the three fields as a function of LS10 i-band magnitude and S/N. PICZL demonstrates a lower outlier fraction for brighter sources while maintaining comparable accuracy to the original photo-z estimates. Additionally, PICZL successfully computes photo-z for sources that are failures in the original methods.
