Extreme Microlensing Events
In a typical microlensing event, the light curve is well fit by assuming that the source is a point, the lens is a single point mass, and the lens is moving in a straight line: the point source-point lens approximation. In these events, the only physically significant parameter that can be measured is the Einstein timescale . However, in some cases, events can be analyzed to yield the additional parameters of the Einstein angle and parallax: and . These include very high magnification events, binary lenses, parallax, and xallarap events, and events where the lens is visible.

Famous quotes containing the words extreme and/or events:
“Individualism, pushed to anarchy, in the family is as ill- founded theoretically and as mischievous practically as it is in the State; while extreme regimentation is a certain means of either destroying self-reliance or of maddening to rebellion.”
—Thomas Henry Huxley (1825–95)
“There are many events in the womb of time which will be delivered.”
—William Shakespeare (1564–1616)
