Left: Cartesian plot of the azimuthal modulation parameters for the HQ objects. The size of the symbols varies with the quality (small error bars) of the data; objects above a set quality level are labeled with their name. Right: similar diagram for models in_A0 (blue) and thm_A0 (red); a cutoff cosi ≥ 0.45 has been applied, similar to what is observed in actual observations. As a visual reminder, two thumbnail images of models are shown along the corresponding axes.
