Definition:

   

      DEPRECATED. This data name should not be used. It has been replaced
      by the ATOM_SITES_AXES data names.

      The definition of the axes used for describing the rotational
      part of the displacive modulation of a given rigid group,
      parameterized by Fourier series, when they are other than the
      crystallographic axes.

;
      a1 and a2 are respectively the long molecular axis
      and the axis normal to the mean molecular plane.
