Like in Fig. 5 but for two microlenses with 25 M_⊙ and 30 M_⊙. Left panel: case where the two microlenses are on a region of the macromodel with positive parity while the right panel is for when the same microlenses are in a region of the macromodel with similar magnification but negative parity. In both cases, the small figure in the bottom-right corner shows the source plane with the caustics and the location of the sources. Only the microimages produced by the white sources are shown in the bigger figures.
