Periodograms of RV and S-index derived from APF data for TOI-6041. From top to bottom: APF RVs, residuals of the RVs after a Keplerian fit to the 88 d signal, and the S-index activity indicator. The vertical pink line marks the planet candidate with a period of 88 d, which shows no corresponding signal in the S-index periodogram. The horizontal lines indicate false alarm probability (FAP; Baluev 2008) thresholds of 0.1%, 1%, and 10%, respectively, from top to bottom.
