>Yes, it gets complicated, doesn't it? This is why I generally recommend trying to use a beam that matches your crystal size.
...or is bigger, right? Diffuse scattering, yes, but more even illumination might be worth it? Generally, James, I have a question: what is the nature of the intensity cross-sections at most beamlines--are they usually Gaussian, or are some flatter? Or I guess, if Gaussian, how much more intense is the peak than the tails? JPK
