Modulated and composite structures dictionary (msCIF) version 1.0.1
Modulation parameters are usually looped in separate lists. Modulated parameters are the atom positions (displacive modulation), the atomic occupation (occupational modulation) and/or the atomic anisotropic (or isotropic) displacement parameters (referred to as modulation of thermal parameters, since the term 'displacement parameters' is ambiguous in this context). _atom_site_occ_Fourier_atom_site_label is the code that identifies an atom in a loop in which the Fourier components of its occupational modulation are listed. This code must match the _atom_site_label of the associated coordinate list and conform to the rules described in _atom_site_label.
