*Numbers in parenthesis in the second and third columns are the student’s t-test confidence level for the above correlation coefficient. Bold type indicates correlations with confidence levels of 95% or higher. Correlations were done with original time series (Original) and detrended time series (Detrended) as marked in the first table row.
