Twin Detection with Improved Robustness
The twin statistic calculated here is based on local intensity differences making it less sensitive to phenomena that tend to confound traditional intensity statistics, such as anisotropic diffraction and pseudo-centering.
For more information on both types of twinning the please see the Introduction to Hemihedral Twinning.
This twinning test was implemented with the program "dataman" available from the Uppsala Software Factory.
This is Version 4. Versions 2 and 3 are no longer in service.
