Conversion of the E_1D(k) spectrum in Fig. 7 to a histogram that represents the relative amount of magnetic energy in bins of log d, where the scale size d is defined by d = 2π/k. The two bumps in the E_1D(k) spectrum now become more pronounced, in particular since we use a linear vertical scale, and the −5/3 power laws get converted into d^2/3 functions that govern the shapes of the left sides of the two peaks.
