Notes. All models consist of the above ring-like disks, halos, and an unresolved stellar source. The distance uncertainty (Table 1) is taken into account in the above uncertainties for the radii. The radii Rin and Rmin are the semi-major and the semi-minor axis of the ring models, respectively. The variable ϑ is the position angle of the semi-major axis.
