The top panel shows the RVs of TOI-1232 from the FEROS spectrograph together with the RV component of the RV + TTV joint N-body model. The model is consistent with two massive planets with an additional RV linear trend component, suggesting a likely third substellar body in the system. The bottom subpanel shows the RV residuals after the model contribution has been subtracted. The bottom left and right panels show a phase-folded representation of the model and RV data.
