Close-up look of the RV GLS periodogram, executed with the publicly available tool Exo-Striker (Trifonov 2019; https://github.com/3fon3fonov/exostriker) after the removal of a linear trend. The two vertical blue lines, around the 29-day signal (indicated by a vertical yellow line), show the main peak aliases due to the two highest frequencies of the window function, in the upper and bottom panels. The three horizontal dotted lines represent the 10%, 1%, and 0.1% FAP levels.
