Notes. The errors are the result of Monte Carlo computations based on the error on the visbilities and closure phases measurements.φM and φD are the M star diameter and the dusty disc/envelope FWHM, respectively. a and θ are the visual separation and orientation of the binary. The last column gives the final reduced χ2 of the fit.
