Notes. Only a limited set of mirror models is shown with respect to the nominal model (Ω₁ ≃ 331°, Ω₂ ≃ 329°, Ω₃ ≃ 110°, i₁ ≃ 86°, i₂ ≃ 86°, i₃ ≃ −24°). The closure phase measurements allow us to discard four of them, namely those with and , because the 3σ level corresponds to a relative increase by 1.051, i.e. . Moreover, the | V | ² measurements do not favour and (3σ is at 1.028, ). The symbol × in the last column indicates we discard this possibility.
