Hi, everyone I have a question about HKL2000. During scaling, there is a check option call absorption correction. I processed the data with and without it checked. With absorption correction checked, my chisq. anomalous is more than 2.0 for all resolution shells. When I leave it out, chisq. anomalous goes below 2.0.
I read through the HKL2000 online manual and only find "direction cosines produce information that can be read by an outside absorption correction program, such as Shelx. The need for it will disappear as the HKL-2000 absorption correction routines are implemented." So do I need to use the absorption correction routinely or just for some trouble dataset. Obviously I don't want to incorporate bad spots. Thanks for your input. Monica
