One of the properties of RS CVn-like binaries is the presence of cyclic fluctuations, sometimes called “migrating waves”, in the V and other broad-band lightcurves. These fluctuations, perhaps due to spots, vary in amplitudes and periods, in the sense that, the longer the orbital period of the RS CVn system, the higher the amplitude of the “wave”, which may be up to 30-35% of the total light variation. Therefore, in short-period (less than one day) RS CVn binaries, these fluctuations are generally difficult to be detected.
