Notes. The star’s identifier in the Kepler Input Catalogue (KIC) is given. Eclipsing systems are marked with an asterisk. The columns νmax and Δν report the frequency of the oscillation power excess and the large frequency separation between radial modes for a given star. ΔΠ1 quantifies the true period spacing of dipole modes. The maximum value of the detected rotational splitting δf is listed. The evolutionary phase RGB describes H-shell burning red giant. Ambiguous values are marked with “?”. The columns R, M, L, and log g report the stellar radius, mass, luminosity, effective temperature and surface gravity from scaling relations, respectively. Teff was adopted from the KIC. The uncertainties of log g are on the order of 0.01 dex and for the temperature typically smaller than 150 K. Porbit gives the orbital period from photometry. The column A lists the maximum amplitude of the heartbeat in a rebinned phase diagram. The error estimate for Porbit and A from the PDM is not reliable due to the remaining contamination of the solar-like oscillations and therefore not given. | ΔRV | reports the maximum difference in radial velocity. Square brackets mark systems for which the orbital parameters could not yet be determined from radial velocities.
