Dependence of CCs on parity. The image shows the sum of the logarithm of magnifications (gray scale), log(μ⁺) − log(μ⁻), from the same ψDM perturbation but for the two parities, μ⁺ and μ⁻. For this particular case, the ψDM perturbation contained both positive and negative fluctuations in mass and corresponds to the yellow square region in the top panel of Fig. 3. The white line represents the ψDM CC when the ψDM perturbation is on the side with positive parity (as in Fig. 3). The black line represents the ψDM CC when the same ψDM perturbation is on the side with negative parity.
