Stellar surface gravity as a function of the effective temperature T_eff for the stars with an agreement between the spectroscopic and seismic evolutionary status classification (in black). Top: Stars with divergent spectroscopic and seismic evolutionary status (pink triangles). Center: Stars identified as RGB by seismology and RC by spectroscopy for which the evolutionary status was confirmed as RGB (blue triangles) or RC (red triangles). Bottom: Same as center panel, but the red triangles correspond to confirmed RC stars identified as RC by seismology and RGB by spectroscopy.
