The Liege solar spectrum is for reference.
Hope this helps.
Very interesting Ken.

When using spectrometers for "terrestrial" applications generally one doesn't have the information overload as seen in the Leige solar spectrum.
In fact if I didn't know what I was looking at I'd swear the graphical representation of the Leige solar spectrum looks more like noise with the exception of the broad absorption band at ~3930A. (Is it due to broadening of the H-Epsilon line?)

I'm impressed with your resolution.
