Name:
'_atom_sites_displace_Fourier_axes_description'

Definition:

   The definition of the axes used for describing the displacive
   modulation, parameterized by Fourier series, when they are other
   than the crystallographic axes.

Example:

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