Result of the point-wise depth inversion for the grid point located at the intersection of slices EF and IJ as indicated in Figure 5. (Left panel) Model space: the dashed black lines indicate the boundaries of the search area. The colored V_S models indicate the best 1000 models retained. The thick grey solid model indicates the median of the 1000 best models found. (Right panel) Data space: the red curve with error bars indicates the observed Rayleigh wave phase velocity dispersion data to fit. The colored dispersion curves are the projection of the 1000 best models onto the data space.
