Abstract
Cross-identification is made for the Catalog of Orbits of Visual Binary Stars and Gaia DR2. At least one component has been matched for 88% systems, for 15% identification is available for both stars. Systems with substantially different parallaxes of components are found, which are the candidates to be the optical pairs. It's shown that published parallax errors in Gaia DR2 are too optimistic.
