The following automatic conversions were performed:

'_exptl_crystal_density_meas' value 'non-mesur\'ee' was changed to
'?' - the value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'calc w =
1/[\s^2^(Fo^2^)+(0.0660P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3' 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^2^)+(0.0660P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3'.
