 Marking atoms 'O(31X)', 'O(32X)', 'O(33X)' and 'O(31Y)', 'O(32Y)', 'O(33Y)'
 and 'O(31Z)', 'O(32Z)', 'O(33Z)' as belonging to disorder groups '1', '2'
 and '3' with the occupancies of '0.4', '0.4' and '0.2' respectively after
 consulting the original publication.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/[\s^2^(F~o~)+0.0002(F~o~)^2^]'
was changed to 'calc'. New tag '_refine_ls_weighting_details' was
created. The value of the new tag was set to 'w =
1/[\s^2^(F~o~)+0.0002(F~o~)^2^]'.
