Comparison of dust clump model and observed SPHERE-ZIMPOL data. First, second, and third columns: 1D cuts at eight different position angles (0°, 45°, 90°,..., 315°) of the intensity I, the normalized polarized intensity I_p, and the degree of polarization p_L maps, respectively. Top, middle, and bottom rows: comparison at 645, 748, and 820 nm, respectively. In each panel, the observed data are plotted with blue lines, while the model is plotted with red lines.
