Notes. The fractions represent the percentage of objects in each subsample defined based on the GZ2 morphology classification, the presence of an AGN according to the BPT-diagram selection criteria, the galaxy position in the SFR-ℳ* diagram, the redshift range, and the dust content defined based on the Balmer decrement.

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.
