calc_fwhm¶

TRXASprefitpack.mathfun.calc_fwhm(fwhm_G: float, fwhm_L: float) → float[source]¶

Calculate uniform fwhm of both gaussian and cauchy component of pseudo voigt profile with fwhm_G, fwhm_L based on Journal of Applied Crystallography. 33 (6): 1311–1316.

Parameters

fwhm_G – full width at half maximum of gaussian part
fwhm_L – full width at half maximum of lorenzian part

Returns

uniform fwhm parameter of both gaussian and cauchy component of pseudo voigt profile
