Notes. .

(a)

Assuming the fainter component is a non-moving background star

(b)

PA is measured from N over E to S.

(c)

Significances are given relative to the last epoch.

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.
