Channel maps at dv = 0.0 km/s (top panels) and two radial profiles of the gas emission along two radial axes (bottom panels). Here, the planet is m_p = 1 M_J, located, respectively, at 10 AU (left column) and 50 AU (right column). The upper and lower slices are the radial profiles taken as shown in the images. The vertical black line shows the planet location, and the dashed gray lines are located at r_p ± 2r_H. Here, we clearly see that the gap is too close to the inner edge to be observed when the planet is located at 10 AU; however, the gap produced by the planet at 50 AU is wide and deep enough to be observed.
