Phase-folded diagram of the analyzed RV measurements using the ephemeris listed in Table 3 (top panel) and corresponding residuals (bottom panel). Measurements from different instruments are marked with different symbols as shown in the legend. The “Lick6,” “Lick8,” and “Lick13” labels are the same as in Birkby et al. (2017) and denote the dewar associated with the spectrograph in use during the observations. Phase 0 corresponds to the inferior conjunction of the planet.
