Detailed Description

A Gaussian line profile.

This profile results when Doppler broadening is dominant.

Member Function Documentation

doublereal profile ( doublereal  deltaFreq )

virtual

The line shape profile

\[ P(\Delta\nu) *\]

as a function of distance from line center \( \Delta\nu \).

This function must have total area = 1.0. Note that this method must be overloaded in each derived class. If the base class method is called, an exception will be thrown.

Reimplemented from LineBroadener.

Definition at line 59 of file LineBroadener.cpp.

doublereal cumulative ( doublereal  deltaFreq )

virtual

The cumulative profile, defined as

\[ C(\Delta \nu) = \int_{-\infty}^{\Delta \nu} P(x) dx \]

.

Reimplemented from LineBroadener.
