Illustration of sparsity vs. linearity for subregions in the example field showing the cutout images, averaged over by all scale combinations with j₂ > j₁. Note that the image cutouts are sorted by their positions on the left panel of Fig. 13, so the original layout does not strictly hold. In general, the patterns of the cirrus present a discernible trend varying with the two WST summary statistics, showing a regulation in cirrus morphology.
