X_Species and x_Clu represent mean values for species-specific and cluster-specific chronologies. Values of n, AGR, s, v, GLK, NET, Rbar, and EPS are calculated on the basis of the undetrended chronologies. n: number of trees per site, AGR: average growth rate, s: standard deviation, v: coefficient of variation, GLK: Gleichläufigkeit, NET: parameter of signal strength, Rbar: inter-series correlation (calculated over 30 years lagged by 15 years), EPS: expressed population signal (calculated over 30 years lagged by 15 years). VaC: mean of the annual variance of the Cropper values per year over the 1941–2000 period calculated for the Cropper series.
