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 been taken.
