Distribution of the discrepancy between the B angle inferred from the synthetic polarized dust emission at λ = 3.0 mm and the mean orientation of the B lines in the simulation as a function of the circular variance V_ϕ for the simulations with standard conditions. All these simulations do not include any initial turbulence (M = 0) and have an initial inclination angle between the initial rotation axis and the magnetic field θ of 30°. The contour lines show the smoothed 2D histogram contour levels at 10⁵ (yellow), 10⁴ (red), 10³ (purple), and 10² (black) counts. The color coded background corresponds to the mean column density.
