Note: N is the total number of stars in our clusters. We have also compared our cluster members with those from Hunt & Reffert (2024), with N_HR24 standing for how many cluster members crossmatch, ordered from the largest to the smallest correspondence.

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.
