Asymptotic power-law distribution of helicity H (in the main window), linking number n (in subpanel (a)), and magnetic flux (in subpanel (b)). The histogram of the data is plotted in double natural log scale, and it is evident that the slope agrees with our theoretical prediction. In the plot, magnetic helicity has a scaling range from exp(96) to exp(100), which is from 10⁴¹ to 10⁴³Mx². The magnetic flux ranges from around exp(51) to exp(53) Mx, which is nearly from 10²¹ to 10²³ Mx. The linking number ranges from exp(−4.5) to exp(−2), which is from around 10⁻³–10⁻¹. In physics, the scaling range could extend beyond the plot, but it would then require a greater amount of data for statistics.
