Kiel diagram for the complete sample of red giant binaries with a spectroscopic effective temperature and surface gravity (either from GSP-Spec or XGBoost). The sample is color coded based on the ratio between the orbital and photometric period. The sources for which the parameters from XGBoost were preferred against the parameters from GSP-Spec are shown as circles with black edges. The background distribution in gray corresponds to a precise GaiaGSP-Spec sample that was selected as in Recio-Blanco et al. (2024).
