Predictions of the 12CO emission for flat, optically thick disks viewed at 80° inclination. The model corresponds to a solution with Rout = 92.5 au, M = 1.6M. The model was convolved with a beam of 0.46′′ by 0.37′′ with a PA = 88°. Left panel: predicted 12CO integrated intensity map; middle panel: 12CO integrated spectra (data en red and model in black); right panel: predicted position-velocity diagram along the disk PA (black and white contours) overlaid on observations (background color map). The blue curve shows the theoretical projected Keplerian velocity profile. In all maps, contours start at 90% of the peak and decrease by .
