Notes. SFR, AV, M and Mdust are derived from CIGALE fit of the multi-wavelength SEDs. The first five rows list galaxies with spectroscopic redshifts; the remaining three correspond to sources with photometric redshifts. For zphot galaxies, errors combine fitting and redshift uncertainties (assuming Δz = ±1). Mgas and τdep are derived from Tacconi et al. (2020) scaling relations.

corrected from μ ¯ L = 2.5 $ \bar{\mu}_L = 2.5 $.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
