Summary plots for the HQ objects. Four panels are shown for each object: (1) visibility squared V² versus projected baseline in units of 10⁶λ; (2) phase closure φ_cp versus the largest projected baseline of each triangle; (3) a halftone image of the circumstellar component resulting from a Ring fit with m = 1 azimuthal modulation, the star’s position is shown by a cross symbol; (4) the (uv) plane coverage. For spectrally dispersed observations, the red, green, blue colors represent wavelengths from longest to shortest. For the V² and φ_cp plots, the absolute value of the fit residuals is shown by the dots at the bottom of the plot.
