Velocity deviations due to the presence of dust along the north of the major axis. Top: velocity deviations measured in the pure Keplerian model at two different spatial resolutions. Middle: ¹³CO integrated emission and dust emission in the original non-convolved model. By definition, the integrated emission is always measured after continuum subtraction. The cavity between 150 au and 260 au is due to the continuum subtraction procedure. Bottom: flux ratio between the outer and inner edges of the synthesized beam.
