Best-fit parameters for the azimuthally modulated ring model.

Parameters [unit] Best ring model Description
fh [–] 0.09 ± 0.01 Fraction of halo flux
fc [–] 0.40 ± 0.05 Fraction of ring flux
i [°] 30 ± 5 Inclination
PA [°] 151 ± 5 Position angle
RK [mas] 1.55 ± 0.15 Half-light radius
RK [au] 0.24 ± 0.02 Half-light radius
w [%] 40 13 + 17 $ 40^{+17}_{-13} $ Relative width
kd [–] −0.5 ± 0.2 Spectral index
c1 [–] −0.23 ± 0.07 Cosine modulation
s1 [–] 0.33 ± 0.06 Sine modulation

χr2 0.97

Notes. The PA is from north to east. The inclination of 0° corresponds to a face-on disk. The reported error bars are deduced from the uncertainty on the ring flux contribution.
