The correlation matrices of the modes of the power spectra shown in Fig. 3. The first two panels show the correlation matrices of the validation and the GAN generated maps, the third panel shows the difference between these correlation matrices. To provide a scale for comparison, in the fourth panel we also show the difference between the validation dataset correlation matrix and the correlations in an auxiliary dataset (see text for details)
