(Left) Comparison of our photoastrometric T _eff values to spectroscopic T _eff measurements from GALAH, APOGEE, and LAMOST. The number of targets that overlap between our catalog and the spectroscopic surveys is shown in the plot legend. Our measurements for cooler stars tend to be lower than all three spectroscopic surveys, with notable differences starting around 4500 K for GALAH and APOGEE, and 3500 K for LAMOST. (Right) Comparison of our temperatures to both photometric and spectroscopic values in Gaia DR3. Our temperatures are typically systematically lower than the Gaia photometric temperatures for stars below ∼4500 K and higher above that value, which can be attributed to either molecular features in cool star spectra affecting T _eff estimates, or a typical overestimation of extinction for nearby cool stars causing spectroscopically-calibrated T _eff measurements to be overestimated (Andrae et al. 2018; Dressing et al. 2019). Our temperatures are typically systematically higher than the Gaia spectroscopic temperatures for stars below ~3700 K and generally consistent otherwise.
