\caption{Stellar variability classes considered in this study, their code, the
number of light curves we used ($NLC$) and their source. Also listed (when relevant for
the class) are the ranges for the parameters $T_{\rm eff}$ and $\log g$ if they
could be determined from the literature. The last two columns list the range for the dominant frequencies ($f_1$) and their amplitudes ($A_{11}$) present in the light curves, resulting from our analysis (Sect.~2.1).}
