Notes. The parameters are the mean (and standard deviation) of the members found with Gaia DR2. We also include radial velocity for those stars available. N refers to the number of members found (and members to compute mean radial velocity).
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.
