Relative RV curve for MML 48. Top panel: We present the three RV datasets CHIRON (red diamonds), FEROS (blue asterisks), and SOAR (green triangles). Each dataset has been shifted by the corresponding systemic velocity (reported in Table 4). Overplotted with a solid black line is the model RV curve fit to all three datasets, as described in Sect. 3.3. Bottom panel: Residuals to RV model shown above for all RV measurements. The errors of the individual RV measurements are shown and may be smaller than the data point.
