Simulated millimeter continuum observations of the three models with (first row) 0.″025, (second row) 0.″13, (third row) 0.″24, and (fourth row) 0.″40 angular resolutions. The beam is shown at the lower left part of each panel with a black contour. The planet is located at 0.″2 radial distance from the center (black/white filled circles). The inset panels in the first row present the inner ±0.″4 of the disks. The dotted circles in the inset of highest resolution Model 1 image indicate the locations of the inner two rings.
