Caption: Figure 5.
Empirical spectra of (a) n and (b) B from Equation (2), with noise-free (dashed) and noise-added (solid) cases (units are arbitrary). Fits to the latter in the range fb < f < fSNR=2.5 are marked in red. (c,d) Variation of slopes obtained from the fits to the empirical spectra of n and B with SNR and smoothness (s).
