The following automatic conversions were performed:

'_exptl_absorpt_correction_type' value 'Gaussian' changed to
'gaussian' 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:

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w =
1/[\s^2^(Fo^2^)+(0.0526P)^2^+0.2377P] 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^)+(0.0526P)^2^+0.2377P] where P=(Fo^2^+2Fc^2^)/3'.
