From spectral line and fitting
The SpectralFit class will do a non-linear least squares solution for a number of simultaneous spectral components. The initial guess of the elements is given in a set of SpectralElements. The final solution is returned in the same set.
To have a contained fitting of spectral profiles to an observed spectrum
