Notes. Columns 1 to 3 list the name of the cluster and the coordinates of its central position. Columns 4 to 8 refer to FOV20pc, listing the associated angular radius, number of members identified divided by the total number of sources within the FOV having Gaia EDR3 proper motions and reliable parallaxes (as defined in Sect. 2.1), and inferred mean parallax and proper motions (uncertainties refer to the standard deviations). The rest of the columns are equivalent to the previous, but related to FOV2pc.

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.
