A model consists of two close microlenses (stars) located in the gravitational field of a massive disc (galaxy). To the left: a system of microcaustics as projected into the plane of a source, and a location of the source (red disc). To the right (a lens plane): a critical curve of the two microlenses and a structure of a microlensed macroimage consisting of separate red spots. Scaling marks at the axes demonstrate the microlens Einstein ring radius. Blue stars show the microlenses location.
