Best-fit model parameters and for the 2-Gaussian model considering only the VLTI/MIDI data. All the parameters are plotted as a function of the wavelength: flux ratio of the compact component (top left); FWHM of the major and minor axes of the compact component (top center); FWHM of the major-axis of the large component (top right); flattening (bottom left); orientation of the major-axis (bottom center); and (bottom right).
