The following automatic conversions were performed:

data item '_chemical_melting_point' value '271-273' was changed to
'272.0(10)' -- the average value was taken and precision was
estimated.

data item '_exptl_absorpt_correction_type' value 'Multi-Scan' was
changed to 'multi-scan' in accordance with the
/home/data/users/saulius/crontab/automatic-downloads/rss-feeds/RSC/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 last updated on
