Decomposition of three synthetic spectra. Three synthetic flow models, with different energy spectra, decomposed using the Shannon number (\(K=1504\)) for the ambiguous patches. The top row (left: increasing; middle: flat; right: decreasing) shows maps of the azimuthal (\(u \phi\)) component of the toroidal flow. The second and third rows illustrate the spatial decomposition. The fourth row shows the summation of the decomposed parts of the flow model, which matches the first row. The bottom row shows the spectral decomposition. Note the different magnitudes of aliasing along the boundaries of each separated region depending on shape of spectra
