Time series of the first four PC coefficients (α’s) during a cycle for the variables of aV and bn (
, 
). A normal distribution of the standard deviation of 0.01 is used for ω, and the coefficients are expanded in Hermite polynomials. Only a single-cluster state case is shown, and the magnitudes of the corresponding coefficients in double-cluster states are comparable to single-cluster case. The insets are blow-ups of the region where the higher order coefficients have their maximum values; 
’s in both cases are already practically negligible
