 Currently, MulensModel supports:
-* Lens Systems: Point Lens, Binary Lens,
-* Source Stars: Single source,
+* Lens Systems: point lens or binary lens.
+* Source Stars: single source or binary source.
 * Effects: finite source (1-parameter), parallax (satellite & annual), binary lens orbital motion, different parametrizations of microlensing models.
