data item '_exptl_absorpt_correction_type' value 'Empirical' was
changed to 'empirical' in accordance with the
/home/data/users/saulius/crontab/automatic-downloads/current/ACS/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 last updated on
2011-04-26.

data item '_symmetry_cell_setting' value 'Monoclinic' was changed to
'monoclinic' in accordance with the
