\({INT}\)

Area under the ACF curve up to 014,15.

\({{INT}}_{0.1}\)

Area under the ACF curve up to the time lag where ACF first decays to 0.1.

\({{INT}}_{0.5}\)

Area under the ACF curve up to the time lag where ACF first decays to 0.5129.

\({{ACW}}_{0}\)

Time lag at which the ACF first crosses zero (after linear interpolation)44,129

\({{ACW}}_{0.1}\)

Time lag at which the ACF first decays to the threshold value of 0.1.

\({{ACW}}_{0.5}\)

Time lag at which the ACF first decays to the threshold value of 0.543.

Hurst

Slope of the linear fit between log of fluctuation magnitude and log of time window size, indicating the strength of long-range temporal correlations124.
