Notes. Column (1) the cluster name (Name), Cols. (2) and (5) are the ellipticities (ecore and eall) of the sample clusters. Columns (3) and (6) are the errors corresponding to the two ellipticities, respectively. Columns (4) and (7) are the orientations corresponding to the two parts in degree (qcore and qall), respectively. Columns (8) and (10) are half-length and half-short axes of the inner ellipses, respectively. The errors of Col. (8) and (10) are displayed in Cols. (9) and (11), respectively. Columns (12) and (14) are half-length and half-short axes of the overall ellipses, respectively. The errors of Cols. (12) and (14) are displayed in Cols. (13) and (15), respectively. The ellipticities (epm) in the proper motion space and its error are presented in Cols. (16) and (17), respectively. Column (18) is the orientation corresponding to Col. (16). The complete table is available in machine-readable form at the CDS.

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.
