Six different baselines.

Baseline ij time N ePMji eVtan
(yr) (mas/yr) (km s-1)

2003–2009 12 6.040 21 10 20
2009–2011 23 2.171 14 28 55
2011–2013 34 1.785 10 34 67
2009–2013 24 3.956 11 15 30
2003–2011 13 8.211 19 7 14
2003–2013 14 9.996 17 6 12

Notes.The first column gives the baseline over years, and the second column shows the sub-indices used, referring to epochs 14. 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.
