Dear All,
Data shold be NEVER refined, no matter whether "data£ is considered
singular or plural. It's the model which is refined.
Beyound this, "data" is plural, as it is the plural of "datum".

Dear Alan/All,
I have a problem with that shorthand expression, particularly in
teaching and training contexts, because students quickly equate this
to “refining the data”. Countless research papers, even coming from
reputable groups and published in reputable journals, contain
statements that “X-ray data were/was refined…”.
Being old-fashioned, I can just about take “data” in singular.
However, “refining one’s experimental data points” is a different matter.
Best,
Ivana

"QPA Profile Refinement" is shorthand for "QPA (using the) Profile
(method of) Refinement :-)
Yes, it is the phase composition that is refined, by fitting the
profile, but I see no problem with the shorthand expression.

Indeed! :-) Nonetheless, whatever the analysis, the profile is never
refined, it is fitted. So I would avoid the misleading use of
“profile
refinement”.
not a big deal, just terminology. Having said my opinion, I
return to
silently follow this interesting discussion.
