Contributions from the even (blue) and odd (magenta) multipoles to the two-point angular correlation function C(θ) in Eq. (13) for (a) ℓ ∈ [2, 401] (top panel) and (b) ℓ ∈ [40, 401] (bottom panel). The delicate balance between odd and even polynomials is clear even at high ℓ for large angles. Selecting a different weighting of each contribution has a strong influence on C(θ) at θ ≃ 180°.
