Comparison of stellar parameters from Hon et al. (2021), Zhou et al. (2024), and SPECIES. Open symbols represent objects with an EEP consistent with an RGB star, while filled symbols correspond to those with an EEP consistent with CHeB stars. The solid red line in the upper panels shows the one-to-one relation. ‘Literature’ refers to the studies by Hon et al. (2021) and Zhou et al. (2024), ‘seismic’ denotes parameters derived through asteroseismology in both studies. Radii are categorised into photo-geometric (from both studies) and seismic (from Zhou et al. 2024 only). The dashed grey lines in the lower panels show the 1-σ dispersion of the residuals.
