Examples of RTC modulations in time series of activity index 
obtained for panel A: total solar irradiance (ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SOLAR_IRRADIANCE/); panel B: long-cadence light curve of KIC 6790311 with P = 16.50 days and Teff = 6202 K (the Kepler mission archive); and panel C: long-cadence light curve of KIC 7346691 with P = 0.731 days and Teff = 5981 K (the Kepler mission archive). The abscissa units ΔJD are in Julian days counted from the data series start moment.
