[Nexus] beam spectrum in NeXus

[Watts Benjamin (PSI)]

Hi Aaron,

   Another interpretation is that the calculated wavelength is a refined version of the spectrum. Therefore, you could use the "variants" feature we were just discussing. It is a more interesting case, however, since the refined value is a different type/shape as the older value, but it is also just as valid for the intended field.


Cheers,

Ben

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)
