Names:
'_atom_site_Fourier_wave_vector_x' '_atom_site_Fourier_wave_vector_y' '_atom_site_Fourier_wave_vector_z'

Definition:

   Wave vectors of the Fourier terms used in the structural model
   to describe the atomic modulation functions, expressed with
   respect to the three-dimensional reciprocal basis that spans
   the lattice of main reflections. They are linear combinations
   with integer coefficients of the independent wave vectors given
   in the _cell_wave_vector_ list. Therefore, a generic Fourier wave
   vector is expressed as k=n(1)q(1)+...+n(p)q(p), where p is given
   by _cell_modulation_dimension. In the case of composites
   described in a single data block, these wave vectors are
   expressed with respect to the three-dimensional reciprocal
   basis of each subsystem (see _cell_subsystem_matrix_W_).
