10
11 double voigt_hwhm ( double sigma, double gamma );
12
14 The function voigt_hwhm returns the half width at half maximum of the
15 function voigt.
16
17 The function voigt returns Voigt's convolution
18
19 voigt(x,sigma,gamma) = integral G(t,sigma) L(x-t,gamma) dt
20
21 of a Gaussian
22
23 G(x,sigma) = 1/sqrt(2*pi)/|sigma| * exp(-x^2/2/sigma^2)
24
25 and a Lorentzian
26
27 L(x,gamma) = |gamma| / pi / ( x^2 + gamma^2 ),
28
29 with the integral extending from -infinity to +infinity.
