Phase folded plot of a four-planet model including candidates e, b, c, and d. The colors represent HARPSpre (purple), HARPSpost (blue), HARPSpw (green), and ESPRESSO (red) observations. In the left panels the model except for the respective planet component was subtracted from the RVs. In the right panels the model except for the planet and GP components are subtracted from the RVs. The yellow dots indicate phase-binned RV.
