Notes. Heliocentric Galactic velocities are in parsec per Myr. To obtain velocities in km s−1 , each component must be divided by 1.0227. Stars are presented here in the same sequence as in Table A.3. In the last column we include references for all data used to produce this table. For each star or stellar system we present sources of: positions, proper motions, parallaxes, radial velocities and masses in this order. In some cases of multiple systems we present individual member references connected with a plus sign.

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.
