Fig. 4


The RV curves for both components in WR62a. The open circles show the RVs for N ivλ4058 Å and N vλ4604 Å emission lines. The filled circles show the mean RVs of some absorption lines for the secondary one. RVs of the emission lines were shifted to match the systemic velocity derived from the absorption lines alone (see text). The ephemeris given in Eq. (1) was used to generate the RV curves.
