Notes. Quoted uncertainties are 1σ errorbars for the velocities (Sana et al. 2013) and 95% confidence interval for the present-day evolutionary masses (Mact) and ages (τ) (Schneider et al. 2018), but for VFTS 661, with the mass estimates taken from Mahy et al. (2020a).
At 3σ from the mean RV value of the complete and NGC 2070 samples but not for NGC 2060 (also not spatially associated with NGC 2060).
Not passing quality checks of Schneider et al. (2018).
Also detected in the proper motion study of Platais et al. (2018).
