No Bob, that was not my point. When you integrate one single crystal
reflection, well separated from the others, what data do you use :
information coded in individual pixels. Have they "bled over" into the
neighboring pixels during the reading procedure? The pixels do not know
whether it was powder or single crystal who sent the photons to them :-)
I do not think that the powder data integrated from an image plate are
more correlated than those measured with a point detector.
Anybody who has developped the image plate software?
Best regards
