(First row): Velocity (left) and dispersion (right) 1D profiles of the observation and models. (Second to forth row): Position-velocity diagrams of C05-NW, extracted along the major (left) and minor (right) axes using a pseudo-slit with a width of 0.245″. The dashed lines represent the 3, 4, and 5σ levels of the observation. The solid black lines represent 0.3, 0.5, 0.7 and 0.9 times the emission peak of the main model A (second row), of Model B (third row), and of the disk-only Model C (forth row).
