This catalogue reports orbital parallaxes exceeding Gaia DR3 measurements in distant binary systems, suggesting systematic discrepancies.
We present the current version of the Catalogue of Resolved Spectroscopic Binary Systems, which, in particular, contains orbital parallaxes. We found that the orbital parallaxes of all distant objects (with d≥ 500 pc) included in the catalogue systematically exceed their trigonometric Gaia DR3 parallaxes and discuss possible reasons for this discrepancy.
