Table 1: Mean excesses $\bar{\delta}_{(U-B)_{0}}$ and $\bar{\delta}_{(B-V)_{0}}$ , with their standard deviations, $\sigma$ , for the samples of active and inactive giant stars. In the last three columns we give the maximum value for the excesses and the number of stars included in the statistics.
Table 2: Name, spectral type, amplitude of the light curve, photometric and orbital periods and interstellar extinction correction for the stars lying below the "zero excess'' line in Fig. 2.
Table 3: Names, spectral types, colour indices at maximum brightness and total amplitudes of the long-term light curves for five stars in Fig. 2 having long-term photometry recorded.
