Notes. The projected rotational velocity distributions of O-type stars (first column) are compared to that of the Cygnus OB2 association, which includes our new O stars combined with measurements from Berlanas et al. (2020). From top to bottom, the comparison samples correspond to the O population in the Galactic region (Holgado et al. 2022), 30 Doradus (Ramírez-Agudelo et al. 2013), Carina OB1 (Berlanas et al. 2025), and NGC 346 (Dufton et al. 2019).
