In the original paper, Salsi et al. (2020), there is a mistake in the calculation of the uncertainty on the angular diameter estimate. Equation (8) should be written as follows:

$\begin{matrix} σ_{θ_{{LD}_{a, b, phot}}} = 2 ln (10) θ_{LD} \sqrt{σ_{θ_{{LD}_{a, b}}}^{2} + σ_{θ_{{LD}_{phot}}}^{2}} . \end{matrix}$ $\sigma _{\theta _{\mathrm{LD} _\mathrm{a,b,phot} }} = 2 \ln (10)\theta _{\mathrm{LD} }\sqrt{\sigma _{\theta _{\mathrm{LD} _\mathrm{a,b} }}^2+ \sigma _{\theta _{\mathrm{LD} _\mathrm{phot} }}^2}.$ (1)

The photometric part of the uncertainty, σ_{θ_{LD_phot}} (Eq. (10) in the paper), also contains an error. The correct formula isfollowing:

$\begin{matrix} σ_{θ_{{LD}_{phot}}} = \sqrt{{(0.1 + a)}^{2} σ_{V}^{2} + a^{2} σ_{K}^{2} + {(0.1 + 0.881 a)}^{2} σ_{A_{V}}^{2}} . \end{matrix}$ $\sigma _{\theta _{\mathrm{LD} _\mathrm{phot} }} = \sqrt{(0.1+a)^2 \sigma _V^2 + a^2 \sigma _K ^2 + (0.1 + 0.881a)^2 \sigma _{A_{V}}^2}.$ (2)

Only considering arbitrary uncertainties of 0.022 mag on both V and K magnitudes leads to a precision of 1.30% on the angular diameter, and not 1.70% as indicated in the paper. The conclusions in the paper remain unchanged.
