Notes. All ages result from isochrone fits. NLC = number of light curves; source: papers used for reddening, age and rotation periods. We assigned arbitrary age errors to M 34 and M 35. For these two clusters we used the published dereddened colors. For M 35 Meibom et al. (2009) did not specify the reddening correction used. See text on the sources of the colors used for the clusters entered in this table.

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.
