Notes.

(1)

Estimated column densities.

(2)

Diameter of the emission region for the compact component assuming a disk morphology.

(3)

BF: Beam filling component.

(4)

E: The disk diameter estimated from our modeling.

(5)

G: only a guess because the size of the disk cannot be constrained on basis of our data.

(6)

The fit to this component is not reliable because the lines suffers from spatial filtering and opacity effects (see text).
