Notes. (1) Period estimated from the fit of the time-variable PA of the continuum azimuthal feature; (2) same as (1) but with the group of epochs at 60 months removed. The mass of the central star is derived by assuming that the feature has a separation ranging from 0.6 to 1.3 au as given by the ring radius ar; (3) same as (1) but with the mass of the central star derived by assuming that the feature has a separation ranging from 1.2 to 1.7 au as given by the half-light radius a.
