Activity detections in the 98 selected stars for the ten parameters analysed (left to right, top to bottom: RV, CCF BIS, CCF FWHM, CCF contrast, CRX, dLW, Hα, Ca IRT-a, b, and c). Stars are shown as a function of their average activity level (measured as the pEW′ (Hα) of the serval template) and mass. Different markers represent the activity signal with the smallest FAP identified in the periodogram of each star (circles correspond to P_rot, hexagons to 1-day P_rot alias, squares to , diamonds to 1-day alias, and crosses indicate that no activity-related peak was found). Symbol sizes indicate the FAP value of the corresponding peak (larger size means smaller FAP), and the points are colour coded as a function of the semi-amplitude of the best-fitting sinusoid to the corresponding period.
