Notes. The samples (of size N) are cut to have zphot < 1.5 for the galaxy subset and zphot < 4 for the AGN subset to allow a more direct comparison between fields. The robust scatter, σNMAD, and OLF, are defined in Eqs. (8) and (9), respectively.

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.
