Comparison of the SoS-Spectro atmospheric parameters (Tsantaki et al. 2022, after calibration) with the literature compilation of high-resolution studies in the PASTEL database (Soubiran et al. 2016), for ≃15 000 measurements, corresponding to ≃14 000 unique stars in common (see Sect. 3 for details). The lighter color corresponds to a higher data density per pixel. The gray points in the background represent the uncorrected data before we applied Eq. (2).
