qspec.models.fwhm_voigt  (  gamma ,  sigma  )[source]

The full width at half maximum (FWHM) of a Voigt profile $$ \delta\nu = 0.5346\Gamma + \sqrt{0.2166\Gamma^2 + 8\log(2)\sigma^2} $$

Parameters:

gammaarray_like

The FWHM of the Lorentzian $\Gamma$ (arb. unit).

sigmaarray_like

The standard deviation of the Gaussian $\sigma$ ([gamma]).

Returns:

outndarray

The FWHM $\delta\nu$ of a Voigt profile.
