Phase-folded RV measurements of HD 20781 with the best-fit solution represented as a black curve for each of the signal foundin the data (from left to right and top to bottom: planets b–e). Error bars include photon and calibration noise, as well as instrumental + stellar jitters derived from the MCMC modeling. The residuals around the solution are displayed in the lower panel. Corresponding orbital elements are listed in Table 6.
