Structure functions of the observed (black) and simulated B_‖. Each simulated is calculated with a different input slope (−9/3 ≤ β ≤ −5/3) with an outer scale of 10 pc, and with α = 2. The input 1D PS slopes of the input B_‖ are shown in the legend. The power-law slopes of the resulting 2D SFs are shown next to the related data. The amplitude of each simulated is sorted arbitrarily for a clear presentation. The teal line represents half of the box size.
