The following automatic conversions were performed:

data name '_chemical_melting_point' was changed to
'_chemical_temperature_decomposition' since the value had been '483
(dec.)'. The value '483 (dec.)' was changed to '483'.

data item '_exptl_absorpt_correction_type' value 'psi scan' was
changed to 'psi-scan' in accordance with the
/home/saulius/struct/COD-crude-data/automatic-downloads/DataCite-retrospective/ACS/depositions/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 last updated on
