Notes. ( * )The orientation angle was fixed in the fitting procedure. To obtain the final values, weights of 0.5 for the closure phases (CP) and 1.0 for squared visibilities (V2) were adopted (see text). The total χ2 given in the table corresponds to such a fitting procedure. The uncertainties of diameter (D) and orientation angle (φ) were obtained using the bootstrapping method.
