Guys,
This appeared in a Rietveld e-mail a bit ago needs a comment:
While I can understand the general rationale for the idea (minimize the
weight of the very strong reflections to the final integrated intensity
for the reflection)
The fact of the matter is that most least squares programs
with spherical
harmonics to account for small discrepancies in some of the peaks (to
give an idea - the Rwp decreased only 1% on correction - if the numbers
mean anything). Is it possible to estimate the level of preferred
orientation, if one uses a spherical harmonics correction? (I know
preferred
only 1% on correction - if the numbers
mean anything). Is it possible to estimate the level of preferred
orientation, if one uses a spherical harmonics correction? (I know
preferred orientation is not the right term to use here, in the first
place)

The data I have collected is on a image plate

The data I have collected is on a image plate (only one frame).
Not sure I understand? If you have a 2D image showing powder rings then
you should have some very good ideas about the level of granularity or
texture

then you should have some very good ideas about the level of
granularity or texture in the sample. Just look for the variation in
intensity versus azimuth? Did you mean a one dimensional image plate?
