Notes. Column 1: ROI. Column 2: hm = ⟨h ⟩ average of singular values. Column 3: σh singularity dispersion (see Eq. (9)). Column 4: Fit error = 
. Column 5: Interval [h1, h2] chosen according to the error bars of singular values in which the statistics
hm,
σh, the standard deviation, and the fit error are computed. Column 6: Standard deviation of each ROI singularity spectrum within the specified interval of h
values shown in Col. 5.
