The following automatic conversions were performed:
'_symmetry_cell_setting' value 'Orthorhombic' changed to 'orthorhombic'
according to '/home/saulius/struct/CIF-dictionaries/cif_core.dic'
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.

The following automatic conversions were performed:

'_chemical_melting_point' value '408/409' was changed to '408.5(5)' -
the average value was taken and precision was estimated.

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^)+(0.0748P)^2^+0.2158P] 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^)+(0.0748P)^2^+0.2158P] where P=(Fo^2^+2Fc^2^)/3'.
