In p. 789 of the published article, Eq. (3) should be corrected to $N_{LD} = 1 / ρ_{LD} = \frac{π^{2}}{4} {(\frac{B θ_{LD}}{λ})}^{2} (1 - \frac{7 u_{λ}}{15}) {(1 - \frac{u_{λ}}{3})}^{-1},$ $\begin{equation} N_{\rm LD} = 1/\rho_{\rm LD} = \frac{\pi^2}{4} \left( \frac{B\theta_{\rm LD}}{\lambda} \right)^2 \left( 1- \frac{7u_{\lambda}}{15} \right) \left( 1- \frac{u_{\lambda}}{3} \right)^{-1} \, , \end{equation}$ (1)with θ_LD the limb-darkened stellar angular radius. When equating this corrected equation to Eq. (2) of Absil et al. (2006), one can derive the expression of the ratio θ_LD / θ_UD between the limb-darkened and uniform-disk angular radii that produce the same null depth, which now agrees with Eq. (5) of Hanbury Brown et al. (1974).

Acknowledgments

The authors are grateful to Bertrand Mennesson for suggesting this correction.
