**Definition:**

Additional Miller indices needed to write the reciprocal vectors of the standard intensities used in the diffraction measurement process, in the basis described in _cell_reciprocal_basis_description. The total number of indices of a given standard reflection must match (_cell_modulation_dimension + 3) and the order of the additional indices must be consistent with the codes given in _cell_wave_vector_seq_id.
