Notes. Columns from left to right are: The system common name, VLBA names (following the KHL17 notation when available, otherwise we used the common name given at radio wavelengths) for the first and second associated radio sources, orbital period (P), the time of passage of pericenter (TP) eccentricity (e), the argument of pericenter (ω), orbit inclination (i), the argument of ascending node (Ω), mass ratio (q), and semi-major axes of first (a1) and second component (a2).

Orbital and mass ratio parameters without given errors indicate that these were taken from the literature.
