 Changing the space group from '-P 3' to '-R 3' after consulting the original
 publication. All related space group information was changed accordingly.

 Antanas Vaitkus,
 2017-07-04

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w=1/(\s^2^(F)+0.003F^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)+0.003F^2^)'.
