It's the model which is refined. Beyound this, "data" is plural, as it is the plural of "datum". https://dictionary.cambridge.org/dictionary/english/datum Norberto 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.

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.
