Comparison of the synthetic images based on the models fid_dres (first and second columns), p1m6fb_dres (third and fourth columns) with the observation taken from Andrews et al. (2018); Isella et al. (2018). The ellipsis at the lower right of each panel visualizes the synthesized beam. The beam size is 49.7 × 41.4 mas for the synthetic images. The rms noise reaches ≈50 μas. The synthetic images are projected with an inclination of 46.7° and a position angle of 133.33°.
