Simulated magnification (in magnitudes) for a source traversing a caustic region. The lens model includes ψDM with de Broglie wavelength 18 pc (red) or 10 pc (blue). Two macromodel magnifications are shown: μ_macro ≈ 100 (red) and μ_macro ≈ 50 (blue). The effects of different lens components are marked. For this figure, the number density of microlenses was reduced to just 1 M_⊙ pc⁻² in order to better show the effect of ψDM. Even at moderate values of μ_macro (blue), the effects of ψDM are very different from standard CDM expectations.
