The original article contains three typos, which are corrected below.

**Section 4.2:** a factor $\frac{1}{d^2}$ is missing in the expression (2) of the visibility. The correct expression for the visibility to consider is:

$$V_{\lambda,\text{disk}}(B_p(i, \theta)) = \frac{1}{F_{\lambda}(0)} \frac{1}{d^2} \int_{r_{\text{in}}}^{r_{\text{out}}} B_{\lambda}(T_r) \epsilon_{\tau} J_0 \left[ \frac{2\pi}{\lambda} B_p(i, \theta) \frac{r}{d} \right] 2\pi r \, dr. \quad (2)$$

**Section 4.2.1:** a modulus symbol is missing at the numerator of the expression (6) of the visibility. The correct expression for the visibility to consider is:

$$V_{\text{tot},1} = \frac{|F_{*}(\lambda) + F_{\lambda,\text{disk}}(i) V_{\lambda,\text{disk}}(B_{p}(i, \theta))|}{F_{*}(\lambda) + F_{\lambda,\text{disk}}(i)} \quad (6)$$

**Section 4.2.2:** a modulus symbol is missing at the numerator of the expression (11) of the visibility. The correct expression for the visibility to consider is:

$$V_{\text{tot},2} = \frac{|F_{*}(\lambda) + F_{\lambda,\text{disk}_h}(i) V_{\lambda,\text{disk}_h}(B_p(i, \theta)) + F_{\lambda,\text{disk}}(i) V_{\lambda,\text{disk}}(B_p(i, \theta))|}{F_{*}(\lambda) + F_{\lambda,\text{disk}_h}(i) + F_{\lambda,\text{disk}}(i)} \quad (11)$$

All the visibility calculations presented in the original article were based on the correct expressions above.
