Overlay of the best TiRiFiC model of the inner disk on the major axis pV diagram. The data is shown in gray-scale and light-gray contours. The model in black contours. For both, the lowest contour level shown is 1.5σ. Subsequent contour levels each increase by a factor 2.5. For the data, the dashed contours also show the −1.5σ level. The vertical dashed lines delimit the inner disk.
