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:

'_refine_ls_weighting_scheme' value 'w = 1/\s^2^(F~o~)' 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^(F~o~)'.
