Differences of DR19 ASPCAP spectroscopic raw Teff and APOGEE DR17 (Abdurro’uf et al. 2022), GALAH DR4 (S. Buder et al. 2025), Gaia-ESO DR5 (S. Randich et al. 2022), and GBS (C. Soubiran et al. 2024) temperatures as a function of ASPCAP raw Teff color coded by raw metallicity. The solid black line shows the running median value.
