Top: Classical microlensing light curve of a point source (dotted curve) and that of a star plus the disk in reflected light (solid curve). A fraction of ﹩\tau =10^{-2}﹩ of the star light is assumed to be reflected by the disk. Bottom: The relative flux difference, ﹩\tau ( A_{d}/ A_{\star }-1﹩). Parameters of the disk are the same as those used for the solid curve in Fig. 3a.
