That one.

The others are the measured stuff that any software could use to 
calculate whatever calculated_wavelength to be used. If you have already 
calculated it, then you can add it.

If you are sure about the calculated being the correct one, then use it 
instead of the foreseen one and create anything to store the raw stuff 
(for instance incident_wavelength_original)
