All the graphs are for HD 204941. Top panel: RVs and the activity index, log(), as a function of time. Lower left panel: RV signal of the planet (continuous line) plus the quadratic drift fitting the magnetic cycle (dashed line). Lower right panel: correlation between the RV residuals (O − C) after removing the planet and the activity index. Small points correspond to all the measurements, whereas large squares represent the same data binned over three months to average out short-term activity.
