Notes. BT stands for the blind test. Bai, Yang, and Galarza present the uncertainties from Bai et al. (2018), Yang et al. (2021), and Galarza et al. (2022), respectively. Bai et al. (2018) only contains effective temperature regression. µ is the center of the Gaussian fit and Δ is the standard deviation. We present the median values of the training uncertainties.
