The Voigt line shape. Kuntz approximation of the Voigt line shape.

Return values
ls_attenuationThe shape function.
xAuxillary parameter to store frequency grid.
Parameters
f0Line center frequency.
gammaThe pressure broadening parameter.
sigmaThe Doppler broadening parameter.
f_gridThe frequency grid.

Original c function call and documention:

int voigt ( long nx, float *x, float y, float *prb, float fak )

Calculates the Voigt-Function times the user-definied value fac with a relative accuracy better than 2*10-6.

If this subroutine is called several times with the same parameter y the numerically expensive coefficents a1..t8 are only calculated once thus further accelerating the algorithm

                  :halfwidth

About 'voigt' : The program was originally written by M. Kuntz in Fortran77 but has been translated into C by Dietrich Feist (f2c) and into C++ by Oliver Lemke and Axel von Engeln. fak is removed from program code. Replaced nx by nf. Replaced prb by ls. Multiplied ls with the factor fac.
