Description
The function voigt_hwhm returns the half width at half maximum of the function voigt.
The function voigt returns Voigt's convolution
voigt(x,sigma,gamma) = integral G(t,sigma) L(x-t,gamma) dt
of a Gaussian
G(x,sigma) = 1/sqrt(2*pi)/|sigma| * exp(-x^2/2/sigma^2)
and a Lorentzian
L(x,gamma) = |gamma| / pi / ( x^2 + gamma^2 ),
with the integral extending from -infinity to +infinity.
