Fig. B.1.


Continuum model results. Continuum visibilities as a function of wavelength along with the best continuum fit in the (u, v) plane. For the V2 and CP plots, the absolute value of the fit residuals is shown by dots at the bottom of the plot. Upper left panel: visibility squared V2 vs. projected baseline in units of Mλ. Upper right panel: CP vs. the largest projected baseline of each triangle. Lower left panel: halftone image of the circumstellar component resulting from a non-Gaussian Ellipsoid fit with m = 1 azimuthal modulation. The stellar position is shown by a cross symbol. Lower right panel: (u, v) plane of the observations.
