Category: atom_site_displace_Fourier
Data type: numb
Must appear in a looped list
containing '_atom_site_displace_Fourier_id'
Must match a value of '_atom_site_Fourier_wave_vector_seq_id'
A numeric code identifying the wave vectors of the Fourier terms used in the structural model to describe the displacive modulation of an atom or rigid group. In the case of a rigid group it applies only to the translational part of the distortion. This code must match _atom_site_Fourier_wave_vector_seq_id.
