The fraction of the trial cosmologies from the bulk ensemble, , with accuracies, averaged over a range of angular scales (0.5−72 arcmin for ξ₊, 8.0−300 arcmin for ξ₋), better than the value, A_c, plotted on the horizontal axis. The grey curves correspond to ξ₊ predictions, magenta to ξ₋. The solid curves result from training the emulator on the noise-free theoretical predictions from NICAEA, whereas the dashed result from training on cosmo-SLICS itself. The decrement in performance when training on cosmo-SLICS is expected due to the added noise in the training set and inaccuracies in the theoretical predictions.
