Sorry, my previous explanation wasn't complete. You would
need to know what the Voigt function parameters are.

v = dblarr(6) ;holds estimates of Voigt function parameters

v(0) Line strength
v(1) Line position in terms of wavenumber array
v(2) Lorentz width
v(3) Doppler width
v(4) Line intercept
v(5) Line slope

x0(i) = array of wavenumbers

Then
yfit = (v(4) + v(5)* x0) * expu

Where "expu" is the rational function approximation
to the Voigt function described in the previous code.
