 Changing the space group from 'P -4 2 3' to 'F -4 2 3' after consulting
 the original publication. All related space group information was changed
 accordingly.

The following automatic conversions were performed:

'_exptl_absorpt_correction_type' tag value 'spherical' was replaced
with 'sphere' value.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc
w=1/[\s^2^(Fo)+(0.018Fo)^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^(Fo)+(0.018Fo)^2^]'.
