Notes. Spectral types are from the Galactic Ο Star Catalog (GOSC, Maíz Apellániz et al. (2013), accessible at https://gosc.cab.inta-csic.es/gosc.php). The last column displays the variability classification by Holgado et al. (2022): Line Profile Variations (LPV), Single Spectroscopic Binary (SB1) or no evidence of radial velocity variations (–).
