Summary of the properties of the time series used in this analysis. The characteristics of the comparison with 
are summarized as: “Mean rms”, which is the average of the rms deviation from the trend, presented as “Slope”, which is the result of the linear fit to the trend (given as per year) and as “Curvature”, which is the maximal distance of the curved trend from the straight line through the end points, divided by the length of the record in years.
