The values for the LES, ESII, STS and German AV are approximate, since variable definitions vary between CPMs

a: values represent summary measures across all iterations of the average difference between the largest coefficient and smallest coefficient across populations b: the average standard deviation (SD) of each coefficient across all populations. All values aim to guide the between-population heterogeneity induced through different σ values
