RV and activity proxy analyses for the residual of the RV time series of IC 4651 9122 after removing the best Keplerian fit. The GLS periodogram (top left panel), the RV versus S index correlation (top right panel), theRV time series (bottom left panel), and the RV phase diagram (bottom right panel) follow similar definitions to those described in Figs. 7 and 9. The Pearson correlation coefficient is 0.27 forRV versus S index and 0.15 for RV versus bisector span when considering the data subset with S∕N ≥ 21.
