Notes. The star’s identifier is the Ecliptic Plane Input Catalog (EPIC; Huber et al. 2016) or the Kepler Input Catalog (KIC; Brown et al. 2011). The frequency of maximum power, ν_max, and large separation, Δν, are given from the A2Z pipeline. The Universal pattern parameters computed with the apollinaire code include ν_max; Δν; the phase offset, ϵ; and the number of fitted radial orders, n_fit. Spectroscopic parameters include effective temperature, T_eff; surface gravity, log g; metallicity, [Fe/H]; and projected rotational velocity, v sin i, all with their respective uncertainties.
