A posteriori comparison between VUDS spectroscopic redshifts and the SED-derived photometric redshifts using the Le Phare code. Top-left: VUDS galaxies with spectroscopic flags 1 (≃50–70% reliable), top right: VUDS galaxies with spectroscopic flags 2 (≃75–85% reliable), bottom left: VUDS galaxies with spectroscopic flag 3 and 4 (95–100% reliable), bottom-right: VUDS galaxies with spectroscopic flags 9 (≃80% reliable). Galaxies in the three different fields are identified as filled squares (COSMOS field), open triangles (VVDS-02h), and open circles (ECDFS). The 1:1 equality relation is drawn as a continuous line, and 15% errors expressed as 0.15 × (1 + z) are drawn as dashed lines. The known degeneracy of photometric redshifts between a Balmer-4000 Å break and a Lyα 1215 Å break is identified by the dotted-dashed line, with 15% errors drawn with dotted lines.
