Category: atom_site_rot_Fourier
Data type: numb
Must appear in a looped list
containing '_atom_site_rot_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 modulation functions corresponding to the rotational distortion of a rigid group. This code must match _atom_site_Fourier_wave_vector_seq_id.
