 Changing the space group from '-P 2yb' to '-P 2yn' after consulting the
 original publication. All related space group information was changed
 accordingly.

The following automatic conversions were performed:

'_exptl_absorpt_correction_type' value '\y scan' was replaced with
the value 'psi-scan' as specified in the replacement file
'src/cod-tools/trunk/data/replacement-values/replacement_values.lst'.
