[NeXus-committee] Concordance paper, ECM

[Tobias.Richter at diamond.ac.uk]

A variant in CIF land is the result of a parameter refinement that comes out of the analysis. 
If e.g. by looking carefully at your data you find the reported monochromator scale was off by 200 meV you want to record both the original intend of the experiment as well as the fact that you now know better. 

Cheers,

Tobias

I am a bit confused about the variant stuff.

If one can have several versions of a parameter, what does it cost to
have that parameter saved as many times as images and/or measurements
need it?

Concerning SIEGBAHNTYPE, IUPACXRAYSMB and knowing nothing about the
context, I would say it is something related to Siegbahn notation
(Kalpha, Kbeta, ...) in one case while and to IUPAC notation (KL3, KL2,
KM3, KM2, ...) on the other one.

Armando
