¹²C¹⁶O (3−2) velocity-channel map of a model with an embedded Jupiter-mass planet as it could be observed using ALMA configuration 14 (1.6 km baseline). The inclination of the disk is 0° (face-on). The outer disk radius amounts to 144 AU and the disk mass to 2.67 × 10^-5 M_⊙. The flux density in Jy/beam is color coded for each individual channel. In contrast to the ideal velocity-channel maps, complex structures are eliminated owing to beam convolution and noise. However, the gap can still be distinguished at the line slopes (±300 m/s).
