Combined RM effects of planets b and c simulated at different times of inferior conjunction of planet c. For planet c, we assumed null obliquity, while we fixed all the other parameters to the value reported in Table 1 and in MG24. For comparison, the RM effect of planet b alone (see Fig. 1) is shown as a black line in the upper plot, while black crosses denote the residuals. The vertical lines denote the propagated ephemeris of planets b and c from MG24.
