Comparison between the measured RVs of the primary (filled dots) and secondary (open dots, when available) of CPD-41° 7742 with the orbital solution from Table 4. The blue and red lines represent the fitted RV curve of the primary and secondary stars, respectively. Top panels: data from Hill et al. (1974, left), Levato & Morrell (1983, middle), and García & Mermilliod (2001, right). Second row, left panel: yields the CAT/CES data from Sana et al. (2003). All other panels correspond to RVs derived in this paper.
