Normalized histogram of the distribution of the alignment angle ξ for dust grains with a size of aeff = 400 nm and a fractal dimension of Df = 1.6 (left), Df = 2.0 (middles), and Df = 2.4 (right), respectively, for typical CNM conditions but with a gas-dust drift of Δs = 1.0. Here, the amplification factor is fmag = 1.0 for all panels. Color-coded is the angle ψ while ζ is the corresponding ratio of attractor points with an angular momentum J in between 3Jth < |J| < Jdisr to the total number of considered dust grains. We note that an alignment angle of ξ = 0° followed by ξ = 90°, respectively, are the preferential configurations for the magnetic field alignment (compare also Fig. 14). For clarity we only plot configurations with a ratio ζ > 2.0 % since distributions with a smaller ζ would only contribute a few but high peaks to the histogram.
