Spectroscopic orbits for six systems with RV data available in the literature; the parameters describing these orbits are given in Table 5. In all cases, these RV data were fit simultaneously with the systems’ imaging data in Table 1, and the corresponding visual orbit shown in Figures 3–7 represents that combined result. Filled points and solid lines mark RV data and model, respectively, of the primary star, and open points and dashed lines are RV data and model of the secondary (if available). The dotted line indicates the systemic velocity.
