I am analyzing a pair of hundred of digitized photographs with
spectra characterized for around half a dozen of Gaussian-like
peaks in them, some clearly isolated and some embedded in fatter
peaks or as shoulders. My questions are the following:

1- Does anyone have some references about spectral data analysis?
As a plasma theoretician that went experimental I am a complete ignoramus
on how to read spectra, including criteria for normalization, differentiating
Gaussians from Lorentzians and the physical meaning of spectral filters
and tranforms.

2- What about non-linear fitting software? I have seen the ad for a
program that fits multiple Gaussians from data taken of a multipeaked
spectrum. Anyone can recomend some UNIX or PC-DOS software that can do
this kind of fitting? Any comments about the reliability of these programs?
