_atom_site_displace_Fourier_axis

Name:
'_atom_site_displace_Fourier_axis'

Definition:

   A label identifying the displacement component of a given atom
   or rigid group that 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. a1, a2 and a3 are defined by
   _atom_sites_displace_Fourier_axes_description.

displacement along an arbitrary a2 axis

a3
displacement along an arbitrary a3 axis
