A tutorial on "how to superimposed spectra and to make sure the comparison is scientifically relevant by normalizing the intensity"

http://astrosurf.com/vdesnoux/tutorial2.html

It uses free software (as in beer) -- maybe it'd be useful for us.

@mathew - just dug up this old note, which shows a method for equalizing area. I'd love to find more literature on the subject, but it's worth a try!

We could/should also try to record a series of fluorescence spectra for a single sample at different intensities, to see if we can equalize them to be roughly the same with this technique.
