**Definition:**

Additional Miller indices needed to write the reciprocal vector of a certain reflection in the basis described in _cell_reciprocal_basis_description. Following the usual convention, such a vector would be expressed as H=h*a*+k*b*+l*c*+m1*q(1)+...+m8*q(8), where h,k,l are the usual _diffrn_refln_index_, and q(1)...q(8) represent the independent wave vectors given by _cell_wave_vector_ and identified by _cell_wave_vector_seq_id. Therefore, the total number of indices of a given 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. These indices need not match _refln_index_m_ values if a transformation of the original measured cell has occurred.
