_atom_site_rot_Fourier_axis

Name:
'_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
   _atom_sites_rot_Fourier_axes_description.

Appears in list containing _atom_site_rot_Fourier_id
The data value must be one of the following:


x
rotation around the a axis

y
rotation around the b axis

z
rotation around the c axis

a1
rotation around an arbitrary a1 axis

a2
rotation around an arbitrary a2 axis

a3
rotation around an arbitrary a3 axis
