_atom_site_rot_Fourier.axis

Definition:

   

      A label identifying the rotation component around a fixed point
      of a given rigid group whose modulation is being parameterized by
      Fourier series. 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_rot_Fourier.matrix_seq_id. Use of   
      _atom_sites_rot_Fourier.axes_description is deprecated and 
      retained only for backward compatibility.
