Data type: numb (with optional s.u. in parentheses)
Enumeration range: 0.0 -> infinity
Units: A ( angstroms)
Unit-cell lengths in angstroms corresponding to the structure reported. The values of _refln_index_h, *_k, *_l must correspond to the cell defined by these values and _cell_angle_ values. The values of _diffrn_refln_index_h, *_k, *_l may not correspond to these values if a cell transformation took place following the measurement of diffraction intensities. See also _diffrn_reflns_transf_matrix_.
