Notes. The stars are divided into color bins according to the limits in b − y in the first column. n is the number of stars in the bin. The third column shows the estimation method used. The subsequent columns give the mean velocities , , , the velocity dispersions σu, σv, σw (in km s-1) and the correlation coefficients ρij = Dij(DiiDjj) − 1/2 (where i,j = u,v,w) from the estimated dispersion matrix. GC means using the full space velocities, including the radial velocities as given by Nordström et al. (2004).

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.
