Notes. Columns up to E are from Carretero-Castrillo et al. (2023), orbital period P_orb and eccentricity e are from Mahy et al. (2022) when available. Numerical values in the radio column correspond to the root mean square (RMS) of the noise level. Comments column contains additional information: ‘HMXB’ for high-mass X-ray binaries (Fortin et al. 2023); ‘γ-RB’ for gamma-ray binaries (Bordas 2024). ‘cand BH’ for systems with candidate BH companions (Mahy et al. 2022; Britavskiy et al. 2023). ‘MS comp’ for Main Sequence companion (Mahy et al. 2022).
