Results from the joint fit of the best model. Top panel: RV time series from HIRES (blue) and CARMENES (orange). Bottom panel: RVs phase-folded to the period of the two transiting planets (HD 260655 b, left; HD 260655 c, right). The error bars are broken into the measurement error and the white noise “jitter” with lighter color. White circles show binned data points in phase for visualization. The black line represents the best fit and the gray shaded area corresponds to the 1, 2, and 3σ confidence intervals of the model.
