The polarization angle χ using Stokes Q and U summed over the spatial domain for each simulation taken at the last snapshot. The colors correspond to different levels of χ, where χ = 0° is polarization in the radial direction, while χ = ±90° is polarization in the azimuthal direction. Each simulation is initialized with a different combination of (τ_s, Z). The circles denote cases with strong clumping, while the crosses denote cases without strong clumping. The squares highlight the two examples explored in more detail in Figures 1, 2, and 3.
