Stars from the OGLE-III catalog, selected for this study: δ Scuti (DSCT), Cepheids (CEP), and RR Lyrae (RRLYR) stars.

The oscillation mode can be “Single” (it is not possible to unambiguously identify the pulsation mode [29], “F” (fundamental mode pulsators), “1O” (first overtone pulsators) or “1O/2O” (double-mode pulsators, in first and second overtone). For RR Lyrae stars, mode is given by the type of the star: RRab are fundamental mode pulsators, RRc are first overtone mode pulsators and RRd are double-mode pulsators (in first and second overtone).
