Left panel: photospheric magnetic activity proxy Sph (in ppm, solid black line) of KIC 3241581 estimated from 1422 days of Kepler observations as a function of time. The individual measurements of the index obtained with the Hermes observations few years after the end of the Kepler mission are represented by the dots. The gray dashed line represents a sinusoid calculated using the main periodicity found in the Sph by a Lomb-Scargle analysis and centered around the first modulation of the Sph. Right panel: same as the left panel but for KIC 10644253.
