Left columns: component correlations r C found in the case of antiphase or ¼-lag cycles, categorized as positively correlated (r C > 0), negatively correlated (r C < 0) or uncorrelated (r C ≈ 0). Multiple classifications are possible for each component correlation, as some component correlations are not consistent across all parameter values. Results in these columns are based on visual inspection; they are not used in the calculation of the associations (r A, see Methods). Right columns: associations r A between the component correlations and the phase relationship.
