The following automatic conversions were performed:

data item '_exptl_absorpt_correction_type' value 'Multi-scan' was
changed to 'multi-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
2011-04-26.

data item '_exptl_crystal_density_meas' value 'Not Measured' was
changed to '?' -- the value is perceived as not measured.
