As title, I would like to know whether any one tried to use all 3 wavelength data merged/scaled
together for the refinement. I tried this on one structure and it appeared to improve the
refinement. I am not sure the theoretical/practical soundness of doing this. If the
crystal is stable, it should give a lot more redudency to the data and help the high resolution
bins. The anomalous/dispersion signals would be messed up but mostly they are not used in
refinement any way. We could even give an average f' and f" for the merged data, or could we? Any
comments?
