Direct comparison between photo-z computed in this work with LE PH ARE and DNNz, within the HSC area for all the EXT (leftpanel) and PLIKE (centralpanel) sources. By construction, true EXT sources should not have spectroscopic redshift exceeding z ≈ 1. It is not possible to decide a priori whether the photo-z are incorrect or if the sources were placed erroneously in the EXT sample due to some issue of the photometry. In the middle panel, we highlight the sources that have spectroscopic redshift higher than 3 in red (see text for details). Right panel: Comparison between photo-z from LE PHARE and spec-z for the sources for which LE PHARE and DNNZ agree.
