The following automatic conversions were performed:

'_symmetry_cell_setting' value 'Monoclinic' changed to 'monoclinic'
according to /home/saulius/struct/CIF-dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.

Id: cif_fix_values 1891 2012-01-12 08:04:46Z andrius 

The value of atom 'O15' tag '_atom_site_aniso_U_12' was changed
from '0.0036)' to '0.003(6)'. The e.s.d. was determined based upon
the e.s.d.s of other values in the same column.
