Continuum-fit parameters and results.

Parameters	Values
Inclination i_D	86.6 ± 0.1°
Inner radius R_Din	<4 au
Outer radius R_Dout	317 ± 5 au
T_Do = T_D (100au)	9.8 ± 0.6 K
Exponent of T_D	−0.3 ± 0.2
Σ_Do = Σ_D (100au)	1.6 ± 0.3 10²³ cm⁻²
Exponent of Σ_D	0.48 ± 0.04
Dust emissivity index β	0.63 ± 0.07
Absorption coefficient κ₀	0.052 cm²∕g
H_Do = H_D (100au)	11.6 au
Exponent of H_D(r), h_d	−1.38

Notes. Dust emissivity is κ(ν) = κ₀(ν∕345 GHz)^β. H_Do and h_D were fixed to the best-fit values from a simultaneous fit of the 220 and 330 GHz data alone.
