The following automatic conversions were performed:

'_exptl_crystal_density_meas' value 'none' was changed to '?' - the
value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value '4Fo^2^/[\s^2^(Fo^2^) +
0.0025Fo^4^]' was changed to 'calc'. New tag
'_refine_ls_weighting_details' was created. The value of the new tag
was set to 'w = 4Fo^2^/[\s^2^(Fo^2^) + 0.0025Fo^4^]'.
