Notes. The first column displays the star names, the second column corresponds to the spectroscopic stellar mass (M_Spec), the third column shows the seismological mass (M_Seis), the fourth column corresponds to the seismological mass inferred from the measured period spacing (M_Seis(ps)), the fifth column corresponds to the number of g-mode periods employed to derive the seismological model and the period spacing (N_Π), and the sixth column is the astrometric mass (M_Astr).
