Notes. The data were sourced from Gaia Collaboration (2023) except the barycentric LOS velocities that are from Soubiran et al. (2018). We used the same approach for the designations as noted in Table 1. The equatorial coordinates are also in the International Celestial Reference System. Spectral types are from the Extended Stellar Parametrizer for Hot Stars module as part of Gaia DR3 Astrophysical parameters inference system (Creevey et al. 2023).
