Tony,
These days many if not most powder instruments (~100% of those at
synchrotron and neutron sources) do some sort of data processing to take raw
measurements and convert them to diffractograms that are used in Rietveld. The
key for how to know if this is done properly is to ask if any e
Hello,
the term "raw data" has become kind of fuzzy in recent times. Most
powder diffractometers nowadays are equipped with some kind of linear or
area detector. The 1D powder pattern in this case is always the result
of some integration, merging, and binning.
I would take "raw" to mean that
Tony, if you bin (add) the raw data you can perform Rietveld refinement as
if you had taken larger steps.
Regards, Alan.
