The following automatic conversions were performed:

'_chemical_melting_point' value '444.6-445.3' was changed to
'445.0(3)' - the average value was taken and precision was estimated.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w = 1/[\s^2^(Fo) +
0.00090|Fo|^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) + 0.00090|Fo|^2^]'.
