Comparison of the effective temperature with literature values. The y-axis represents the values published in Stassun et al. (2019); Paegert et al. (2021), and the black dashed line represents equality. We note that the apparent tail of deviations towards lower temperatures is comprised of stars for which the RV was not known, and for which the stellar parameter determination failed. All stars with a missing RV value and possible errors in the catalogue are marked via the VFLAG column in our catalogue.
