Notes. The first column list the Tycho ID. The second column indicates the RV catalogue (see Table 1). Columns 3, 6, and 9 are 
, , and 
respectively. The columns labelled 5% and 95% are the bounds of corresponding confidence intervals. Columns 12–14 (“% samples”) indicate the percentage of surrogates for each object for which dph is below 0.5, 1.0, and 2.0 pc respectively. Columns 15–20 list the nominal parallax (ϖ), proper motion (μ), and radial velocity (vr) along with their standard errors. Objects with potentially problematic data have not been excluded. The online table at CDS includes all objects with 
pc (in a handful of cases for 
pc the ID is Hipparcos, not Tycho).
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.
