Frequency of occurrence of DFA scaling exponents of RTT time series calculated for first (a), second (b), and third (c) days, day-time measurements. Scaling exponents have been calculated for consecutive 1000 data windows shifted by 100 data steps. Crosses: GTU, squares: Harvard, diamonds: UCLA, triangles: USC, and circles: USTC.
