Resulting distribution of the polarized flux F_p for the D03 disk model (see Table 1). The outer left panel shows the polarized flux distribution as a result of scattered stellar radiation under an inclination angle of i = 45° and a wavelength of λ = 730 nm. The plots show the polarized flux through the center of the disk along the horizontal direction (left plot), along the vertical direction (middle plot), and the bisecting line (right plot). The red lines show the results from the MC3D code, the blue ones the results from the POLARIS code, and the gray lines show the errors between both codes.
