spectrochempy.pseudovoigtmodel

class pseudovoigtmodel

A pseudo-Voigt model.

The pseudo-Voigt profile is a linear combination of Lorentzian and Gaussian profiles with the same centre and FWHM:

\[f(x) = (1 - ratio) L(x) + ratio G(x)\]

The convention follows the existing Voigt parameterization: ratio=0 is pure Lorentzian and ratio=1 is pure Gaussian.
