Notes. The values are adopted from Shenar et al. (2016). The orbital period Porb and radial velocity amplitudes KWR for the WR starand KO star for the O star (if known) are the values derived by Foellmi et al. (2003) and Foellmi (2004). The exception are the WR stars 5A and 5B which reside in thesame system; their orbital parameters are adopted from Koenigsberger et al. (2014).
