 Changing the space group from 'P -2y' to 'C -2y' after consulting the
 original publication. All related space group information was changed
 accordingly.

 Antanas Vaitkus,
 2017-07-06

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '1/\s^2^(F~o~)' 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~)'.
