Percentage of outliers versus spectroscopic redshift (upper panel) for the point-like sources. At each redshift, we calculate the percentage of outliers for all sources above this redshift. The bottom panel show the distribution of the training samples with available spectroscopic information. The performance in the DES field using TPZ (blue-dashed-dotted) and LePHARE (red-solid) is compared across different redshifts. For reference, we show the performance of LePHARE algorithm for the 4XMM-DR13 sources using different optical photometry adopted from Ruiz et al., (in prep.), such as SDSS (black-solid), PANSTARRS (gray-solid) and SKYMAPPER (gray-dashed). Finally, we present the LePHARE performance of z ≥ 5 sources of Yang & Shen (2023).
