Comparison of the normalized total flux F_I (top), the normalized polarized flux F_Q, and the polarization P seen along an inclination of 20 (top left), 40 (top right), 60 (bottom left) and 90 deg (bottom right) for the model with mirror symmetry (i.e., two blobs) and without (i.e., one blob). The blob(s) is (are) characterized in all cases by V_blob = 4000 km s⁻¹, δV_blob = 1000 km s⁻¹, β = 10 deg, and N_e,fac = 20, corresponding to a radial blob optical depth of 0.436.
