The Voigt profile (named after Woldemar Voigt) is a probability distribution given by a convolution of a Cauchy-Lorentz distribution and a Gaussian distribution. It is often used in analyzing data from spectroscopy or diffraction. See more In spectroscopy, a Voigt profile results from the convolution of two broadening mechanisms, one of which alone would produce a Gaussian profile (usually, as a result of the Doppler broadening), and the other would produce … See more Tepper-García Function The Tepper-García function, named after German-Mexican Astrophysicist Thor Tepper-García, is a … See more The Voigt profile is normalized: $${\displaystyle \int _{-\infty }^{\infty }V(x;\sigma ,\gamma )\,dx=1,}$$ since it is a convolution of normalized profiles. The … See more The Voigt functions U, V, and H (sometimes called the line broadening function) are defined by See more • http://jugit.fz-juelich.de/mlz/libcerf, numeric C library for complex error functions, provides a function voigt(x, sigma, gamma) with … See more WebJul 1, 2004 · This argument can be verified by numerically computing the Voigt profile. Figure 2 shows the normalized Voigt, Lorentz, and Doppler profiles when the Doppler half-width is the same as the Lorentz half-width, the same conditions described for Fig. 1.The Voigt profile is calculated with the approximate formula given by Humlicek (1982).We …
