Notes. We only list the groups that represent real clusters at a 40% threshold in completeness and homogeneity (highlighted in boldface). The number of stars found in each group is indicated, (NFOUND), and for each corresponding real cluster, we also indicate the number of stars found with respect to the total number of cluster stars (
). For each recovered cluster, the completeness and homogeneity of the recovery is also indicated.
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.
