Notes. Name, type, and radial velocity (vr) are taken from SIMBAD, except for the names Cyg X-1 (for HD 226868) and σ2 CrB (for sig CrB A). An ellipsis (…) means the same data as in the line above. Positions α(t), δ(t) are barycentric and refer to the epochs in the fourth column. Uncertainties (in mas and mas yr−1) are given after the ± sign; for α they are σα* = σαcos δ. Positional data without uncertainties were not used in the solutions.
