    • The constant C is often quoted in the literature with a value C = 2 [20,26,14]. The more precise calculation here (Appendix C) leads to the value C= 1.8456.

    • note
    • We note that we have made a similar change of variables for some of the data shown in Ref. [21] in order to have the exponential tail systematically on the left-hand side of the figure. The SOC data for the forest fire, Bak-Tang-Wiesenfeld and Sneppen models, and the correlated extremal data are treated this way.
