Top: phased RV plot for WR 140. Archival RV measurements are shown in blue (Fahed et al. 2011) and green (Thomas et al. 2020). The RV measurements from HERMES (red) using C IV strong lines have been shifted by 19 km s−1 in order to convert relative RV measurements to absolute ones. Bottom: same for WR 113. Archival RV measurements are shown in blue (Hill et al. 2018) and green (Massey & Niemela 1981). The RV measurements from HERMES (red and yellow) have been shifted by −135 km s−1 in order to convert relative RV measurements to absolute values.
