Summary of stellar parameters for solar analogs from B18 in purple, GALAH DR4 (S. Buder et al. 2025) in orange, APOGEE DR17 (Abdurro’uf et al. 2022) in blue, and Gaia RVS (R24) in pink. Left: histograms of distances probed by each survey. B18 surveyed stars nearby in the solar neighborhood, while our samples from Gaia, APOGEE, and GALAH span further distances. Middle: T_eff–﹩\mathrm{log}g﹩ plane of solar analogs in each sample. Right: [Fe/H]–[α/Fe] plane of solar analogs in each sample. GALAH, APOGEE, and Gaia are shown as 3σ contour regions rather than individual scatter point distributions for clarity in the middle and right panels.
