Six different baselines.

Notes.The first column gives the baseline over years, and the second column shows the sub-indices used, referring to epochs 1−4. N denotes the number of knots with proper motions larger than 2σ. The estimated errors in proper motion speed ePMji are converted to errors in the tangential velocities (assuming d = 415 pc).
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.
