Extended Data Fig. 5: Results on selection of the best-fitting model through correlation analysis between experimental and simulated radar data.
From: Radar evidence of an accessible cave conduit on the Moon below the Mare Tranquillitatis pit
(a) Values of the correlation coefficient (see Methods) between experimental and simulated data versus the roof and floor slopes. The black arrow represents the uncertainty with respect to the best fit model denoted as B. (b) Maximum value of the correlation coefficient versus the roof’s slope. As a result of the radar ambiguity in determining the cave parameters, the two models denoted as A and B are possible. The range of plausible slopes for which the correlation coefficient yields a high value is in line with what predicted by the radar geometric model for estimating the cave conduit slope from the radar image (see Methods). The correlation coefficient value for the simulated data based on the sole Wagner and Robinson overhang model17 is equal to 0.66.
