Notes.
We provide the values for the whole sample for the sake of homogeneity with the other surveys. The medians of the two peaks are −0.37 and 0.53 km s−1, with standard deviations of 0.19 and 0.15 km s−1, respectively (see panel h of Fig. 6 and text for details).
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.
