Exponents of multifractal detrended fluctuation analysis for the third band of integrated power in 2014 and 2017. a) Generalized q-order Hurst exponents h(q) for q = −5 to q = 5 for density fluctuation power in 2014. b) Mass exponent τ(q) for q orders similar to a). c) The graphical representation of singularity exponent α versus singularity dimension f(α) recognized as the multifractal spectrum. The arrow represents the difference between α’s maximum and minimum. Panels d) to f) are comparable to panels a) to c) for the same integrated power band in 2017.
