Astrometric Radial Velocities. III.

The astrometric radial velocities are determined independent of spectroscopy. Table 1 gives the space velocities and internal velocity dispersions of the clusters and associations.

The electronic Table1 (Table1.dat) is an extended version of Table 1 in the journal paper, now including the full covariances of the space velocity components as well as the space motion in spherical coordinates. Table 2 gives the astrometric radial velocities and kinematically improved parallaxes for the individual stars. The electronic Table 2 is an extended version of Table 2 in the journal paper, now including all clusters and associations studied; results using data from both the Hipparcos and Tycho-2catalogues, as well as the standard errors for all deduced quantities.
