Notes. The disk sizes are calculated from cumulative radial profiles (Tripathi et al. 2017), which in turn are calculated from the azimuthally averaged intensity profiles. The 3.1, 2.1, 1.3 and 0.87 mm disk sizes are calculated using the intensity profiles in Fig. 3, whereas the 0.65 mm disk sizes are calculated from the intensity profile in Fig. 2. We do not report R99 for the 2.1 and 3.1 mm profiles because it coincides with R95 due to lower surface brightness levels. (a)The radius enclosing 68% of the total flux density. (b)The radius enclosing 95% of the total flux density. (c)The radius enclosing 99% of the total flux density. (d)The 3.1, 2.1, 1.3 and 0.87 mm outer ring fluxes are calculated with the imstat task in CASA with masks at 79 and 93 au, whereas the 0.65 mm one is calculated from the best-fit MCMC model. (e)The mass of the outer ring in multiples of the mass of the earth. Refer to Sect. 3.4.2 for further details.
