The coupling parameter estimated using a choice of cycle troughs that minimizes the error-mean-square of the regression model (with standard error of slope estimated from regression in the usual way) based on a search of 2,000 resamples of cycle minima. 

Significance of the coupling parameter reported in previous column (based on a t test of (c/SE(c)). 

The slope of the same regression analysis with points associated with standardized residuals greater than |1.96| eliminated from the analysis (significance levels are unchanged). 

§

The average coupling parameter from 2,000 resamples of cycle minima (in parentheses, standard error, computed as square-rooted averaged squared standard error of parameter estimates from each choice). 

Significance of the coupling parameter reported in previous column (based on a t test of (c/SE(c)). The figure in parentheses is the % of trough resamples yielding slopes significantly less than 1. 

The variance of the residuals (σInline graphic) associated with the best fitting regression model (almost identical to the average variance of residuals). 

**

The averaged measure of asynchrony along the time-series evaluated using the 2,000 resamples. The upper 95% confidence intervals of these variances (in parentheses) are all less than Inline graphic
