Notes. All entries adopted from FMG unless otherwise specified. Stars analyzed here are denoted with large fonts.
Spectral type of the primary variable (WN3/11), but WN6h (FMG) corresponds to the most recent spectra used here; all other entries adopted from Koenigsberger et al. (2014), and references therein.
Adopted from Perrier et al. (2009).
Orbital parameters adopted from Niemela et al. (2002), whose solution is more accurate than that presented by FMG (FMG).
Moffat et al. (1990), St-Louis et al. (2005), and references therein.
