The sample, consisting of 804 Hipparcos visual binary systems with known orbits which were determined from ground-based observations and not analyzed in Paper I (Bartkevicius and Gudas, 2001, Cat. ), is selected from the Fifth Catalog of Orbits of Visual Binary Stars (Hartkopf et al., 2000). Hipparcos catalogue number, the identification of the star in other catalogues, the equatorial coordinates for 2000.0, the magnitude V, the color index B-V for the combined light of the system, and a spectral type are taken from the Hipparcos Celestia Catalogue (ESA 1998, Cat. ). The trigonometric parallaxes are compiled from the Hipparcos Celestia Catalogue . For several stars the improved Hipparcos results are used and the dynamical parallaxes are also calculated. The mean relative error of the weighted mean parallaxes is about 12%. For the bulk of the stars proper motions are taken from the Hipparcos and Tycho-2 catalogues. The average relative error of the weighted means of proper motion is about 4%. Radial velocities for 474 stars are compiled from several radial velocity catalogues. The mean value of the standard error of the sample is about 2.5km/s. 330 (41%) of the stars belonging to the sample lack radial velocity determinations. The computed galactic velocity components and other kinematical parameters are used to divide the stars into kinematical age groups.
