  [text: Because of a programming error the square root of the power spectrum was used instead of the power spectrum itself. This means that the correct result is that we observe S(f) ~ 1/f² noise (instead of 1/f noise as stated). Thus the slope in Fig. 3 is cphi = 2 +- 0.06. We conclude that 1/f² noise is observed, as in the sandpile experiments]

  [Comment: this is the paper that pointed out that the 1/f noise claimed in Bak,Tang,Wiesenfeld (1987) paper is actually 1/f² noise.]
