Automatic conversion scripts had previously changed 
'_atom_site_refinement_flags' tag values 'd' into 'D' as recommended by 
'cif_core.dic' version 2.4.1. However, manual inspection revealed that the 
underlying problem was actually related to a wrong tag names inside the 
atom site loop. The following changes were performed to resolve the problem: 

* '_atom_site_refinement_flags' tag was changed to '_atom_site_calc_flag'
* '_atom_site_calc_flag' tag was changed to '_atom_site_site_symmetry_order'
* '_atom_site_disorder_group' tag was changed to 
  '_atom_site_refinement_flags_posn'

The following automatic conversions were performed:

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