Scale-averaged wavelet coeff is used to estimate the variance of high-frequency fluctuations and local Hurst exponent is interpreted as an estimator of the correlation time in the high frequencies. Here in same issue because published in same paper and might be specifically suited for DO-events. Both are CSD indicators and hence come with usual caution.
