Updating space group information and adding the symmetry operation list.
Antanas Vaitkus,
2018-06-18
The following automatic conversions were performed:
'_refine_ls_weighting_scheme' value 'w=1/[\s^2^(F~o~)+0.005F~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~)+0.005F~o~^2^]'.
