Distribution of the theoretical 𝒜₁ asymmetries for the quad1 ℓ = 2 multiplet. Each panel is a different set, as indicated in the top-left corner of the panel. The vertical orange line indicates the observed asymmetry. Since the multiplet is not complete, the 𝒜₁ asymmetries have two observed values, which can be seen in the left panels as the two separate lines. The scale of the x-axis in the right panel is too large to show the two values. The radial orders associated with these asymmetries can be found in Table 2 under the quad1 multiplet.
