Notes. The parameters M, R, log g, Teff, and [Fe/H] refer to stellar masses, radii, surface gravities, effective temperatures, and metallicities, respectively. The subscripts “dyn” and “seis” stand for dynamical modeling and asteroseismic scaling relations, respectively. In the comment column, em. stands for spectral “emission”; Ca H & K indicate the calcium lines at 3968.5 and 3933.7 Å, respectively, and Hα the hydrogen Balmer line at 6562.8 Å. The comments “RG eclipsed” and “Cmp eclipsed” indicate that only one type of eclipse is visible in the light curve, either the RG is eclipsed (RG) or the companion (Cmp). For SB1 systems, the parameters of the companion stars are deduced by combining asteroseismic masses and radii of the RG with the mass function obtained from light curve and radial velocity modeling. For RC stars, the age uncertainty may be underestimated (see discussion in Sect. 3.4). We could not determine the mass, radius, and age of the giant component of KIC 4473933 because this binary is an SB1 (see Fig. 4) and its power spectrum has no detectable oscillations (see Fig. A.2). The values of Teff, [Fe/H], Porb, and e are reported to provide a view of each system at a glance. The exact values with uncertainties are shown in Tables 1 and 2.
