Notes. We give the offset of the ellipses from the central star position, as well as the size of the major and minor axes for each fitted feature. We also give the size of the semi-major axis in au, since it directly corresponds to the physical radius of the de-projected rings. Inclination and position angle were fitted simultaneously for all structures resulting in a single value.
