Notes. Column 1 lists the object name, Cols. 2 and 3 the average heliocentric velocity and its dispersion, Cols. 4 and 5 give the measured proper motion, Col. 6 the average correlation coefficient between them, and Cols. 7 and 8 the average metallicity and its dispersion. Above the line we show the values calculated from all possible members, and below the line those from the certain members. We indicate in bold which determination we prefer (see main text for details). The upper limits refer to the 90th percentile of the pPDFs.
