SB9 systems from the present study with a DR3 entry in the period - parallax plane. The symbol size is proportional to the RUWE indicator (Lindegren et al. 2021). The color codes are as follows: cyan: no RV available from Gaia DR3, magenta: N_RV < 10; orange: G_RVS < 5.5, dark green: astrometric binary, red: astrometric acceleration solution, green: SB1 or SB2, black: no binary detection in the NSS DR3 catalogue (even though the RV χ² p–value is lower than 10^–4).
