'_cell_reciprocal_length_a' '_cell_reciprocal_length_b' '_cell_reciprocal_length_c'


   The reciprocal-cell lengths in inverse angstroms.  These are
   related to the real cell by:

   recip-a = b*c*sin(alpha)/V

   recip-b = c*a*sin(beta)/V

   recip-c = a*b*sin(gamma)/V

   where V is the cell volume.
