Expected kink in the channel maps for a thermal mass planet in a disc with h_p/r_p = 0.05 (left column) and h_p/r_p = 0.1 (right column), resulting in a planet mass of m_p ≃ 0.02 M_J and m_p ≃ 0.67 M_J, respectively. We arbitrarily set the inclination of the disc to i = −45°. Top row: channel maps obtained from the velocity field of the simulation. Middle row: channel maps obtained from the velocity field of the analytical model. Bottom row: intensity residuals between the channel maps obtained from the velocity field of the simulation and the analytic model.
