Definition:

   

      The coefficient corresponding to the x-harmonic function 
      defined by _atom_site_displace_xharm.atom_site_label,
      _atom_site_displace_xharm.axis and _atom_site_displace_xharm.order.  
      Atomic or rigid-group displacements must be expressed as fractions 
      of the unit cell or in angstroms if the modulations are referred to some
      special axes defined by defined by the items belonging to the 
      ATOM_SITES_AXES category, through _atom_site_rot_xharm.matrix_seq_id.
