Notes. In boldface parameters used to create artificial galaxies (Sect. 5). Values of input parameters used for the SED fitting with CIGALE. Bold face values are used for the mock catalogue in Sect. 5.
In case of two populations, AV corresponds to the attenuation of the youngest population and a reduction factor of 0.5 is applied to the visual attenuation of the older stellar population (see text).
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.
