Periodogram of RVs and activity indicators of HD 88986. From top to bottom: HIRES and HIRES+ S-index, SOPHIE+ S-index, bisector, RVs, and residuals of RVs after Keplerian fit on the 146.1 d. The vertical red line illustrates the planet candidates on 146.1 d, which have no corresponding peak in activity indicators. The vertical gray strip marks the estimated rotational period of the star. Also, the horizontal lines show the FAP level of 10, 1, and 0.1%, respectively (Baluev 2008).
