Meridional profiles of the disk temperature (left) and synthetic channel maps of C¹⁸O emission (right) for simulations S1 (top), S2 (middle), and S3 (bottom). Please note that the planet is shifted to 85 au in the bottom row. Therefore, the radial extent of the simulated disk, the wavelength of the synthetic image, and the centering of the inset differ from simulations S1 and S2.
