Synthetic images of the ¹³CO (J = 3−2) emission from our simulation with M_P = 2.0 M_Jup after an evolution time of 4 × 10⁴ yr. We compute the images at two different channels: v = 5.0 km s⁻¹ (top panels) and v = 7.5km s⁻¹ (bottom panels), with a velocity resolution of 0.5km s⁻¹. We use three different circular beam sizes: 0.03″, 0.02″, and 0.01″ (FWHMs, from left to right), indicated by the white circles in the lower-left cornel of each plot. The blue dot represents the planet position at the azimuthal angle ϕ = 145° (relative to the angle ϕ = 0°, which is located at the disk major axis indicated by the dashed white line in the top-left panel).
