Hi All,

I was hoping I could get some clarification on the difference between
Rsym and Rmerge.

Does the Rsym represent the differences in the symmetry related
reflections on a single image?

or,

Does it represent the differences in the symmetry related reflections on
a single crystal?

If it is the later, what about low and high resolution data collections?

Do you report an Rmerge because you are comparing 2 different data sets?
