_atom_site_displace_xharm.axis

Definition:

   

      A label identifying the displacement component of a given atom
      or rigid group that is being parameterized by x-harmonic functions. 
      a, b and c are the basic lattice vectors of the reference  
      structure. For composites they refer to the reference structure of 
      each subsystem. a~1~, a~2~ and a~3~ are defined by the
      items belonging to the ATOM_SITES_AXES category, through 
      _atom_site_displace_xharm.matrix_seq_id.
