Fig. 7


Cross-validation errors for end-of-mission spectra of UCD stars at G = 20. The upper panels show the errors in the Teff estimates for the GP model (left) and the k-nearest neighbours model (right). The lower panels show the corresponding errors in the log   (g) estimates. The colour code for the error scale is shown in the right-hand side of each row. Effective temperatures are measured in Kelvin and gravities in cm/s2.
