Response of scanning Fabry-Perot interferometers to asymmetric spectral line profiles.

A detailed discussion of the effect of adding the dispersion-shaped component to the Lorentzian profile on the resulting line profile recorded by an ideal scanning Fabry-Perot interferometer is presented. An analytic correction to the Ballik formula for the response of a Fabry-Perot interferometer is derived which makes it possible to determine quantitatively the magnitude of the collision-time asymmetry in the line profiles.
