Confrontation of log-Gaussian statistics with RWST statistics on logFBM synthetic data (a), observations (b), simulations (c), and observation-simulation pairs (d). As expected, no log-Gaussian degeneracies are found for the logFBM data (a). However, some are found for the other cases (b,c,d). To investigate the log-Gaussian degeneracies in the observations, six pairs of patches, whose locations on the scatter plot (b) are given by the red stars, are shown in Fig. E.1. Only five stars are actually visible, but two of them are overlapped at the horizontal coordinate x = 10.
