Maps of observed averaged number of scattering with an inclination angle of 90^° at 800 nm with MontAGN. Polarisation vectors are shown, their lengths being proportional to the polarisation degree and their position angles representing the polarisation angle. The first two images are for models with silicates and electrons, the last two images for models with silicates, graphites, and electrons. The first and third images correspond to model 4, the second and fourth to model 5.
