The following automatic conversions were performed:

'_exptl_absorpt_correction_type' value 'Multi-scan' changed to
'multi-scan' 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:

'_refine_ls_weighting_scheme' value 'w=1/[\s^2^(Fo^2^)+(0.0382P)^2^]
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^)+(0.0382P)^2^] where
P=(Fo^2^+2Fc^2^)/3'.
