Moment 0 (1st, 3rd and 5th columns) and combined channel maps at dv = −1.0; 0; 1.0 km/s (2nd, 4th and 6th columns) for different configurations: the planet mass increases from left to right; the 3 first rows correspond to the planet located at 50 AU, while in the 3 last one the planet is located at 100 AU; for each planet location, the disk distance is increased from top to bottom (40pc, 100pc, 130pc). We show the channel maps issued from CASA in Jy/beam with the resulting beam shown in red in the bottom left corner. Here, the disk’s mass is 10⁻³ M_⊕ of CO. The observability of the planetary gaps depends on whether the gap is resolved or not.
