The following automatic conversions were performed:

'_exptl_absorpt_correction_type' value 'Empirical' changed to
'empirical' according to
/home/data/users/saulius/crontab/automatic-downloads/rss-feeds/RSC/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.
