Name:
'_atom_sites_rot_Fourier_axes_description'

Definition:

   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.

Example:

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