_cell_length_

Names:
'_cell_length_a' '_cell_length_b' '_cell_length_c'

Definition:

   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 the diffraction intensities. See
   also _diffrn_reflns_transf_matrix_.


The permitted range is 0.0 -> infinity

Type: numb
