Notes.

The most massive galaxy of each group, used in the calculations of the dynamical masses in Table 5.

Galaxies with no 24 μm data. The SFRs, sSFRs, and LIR of these systems are not well constrained.

An AGN in their nucleus dominates their mid-IR emission.

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.
