**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_).
