Notes. For Gaia data, the typical uncertainty is defined as the median value of the upper confidence level (84%) minus the lower confidence level (16%) for the atmospheric parameters of the sample (Creevey et al. 2023; Fouesneau et al. 2023; Recio-Blanco et al. 2023). For the other surveys, the typical uncertainty is defined as the median value of the errors in the atmospheric parameters of the sample (Abdurro’uf et al. 2022; Buder et al. 2024). N refers to the number of common stars.
