Notes. Columns (1) and (2) show the number of breaks needed to fit 12+log(O/H) and log(N/O) radial gradients respectively. Column (3) shows the total number of galaxies for each group. Column (4) shows the relative number of galaxies with respect to the group. Column (5) shows the relative number of galaxies with respect to the whole sample.
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.
