Notes. In the first tier of galaxies, the two lines identified in the spectrum are employed to estimate the spectroscopic redshift. For the galaxies in the second tier (i.e., in those with a single line identified), we assume the spec-z as the redshift allowed by the visible line with the best agreement with the photometry. For each galaxy, we also report the photometric redshift computed by Talia et al. (2021) and that computed through SED fitting with CIGALE following Gentile et al. (2024) after adding the 3 mm continuum point.
