Separation between the components of HD 90823 inferred with HAM as a function of wavelength, expressed in units of λ/D (blue points) and expressed in milliarcseconds (red points). The blue line is proportional to 1/λ. The red line is a weighted average of the measured separations in milliarcseconds. The number of data points is larger than the number of independent measurements (∼4).
