6.9.2010 - Kamil Sedlak

Browse Source 
1) bug found and corrected in the field-map extrapolation of the electric 
     and magnetic fields for the spin-rotator (3DEOpera and 3D and 
     symmetryType=1 or 2). The documentation was updated.
  2) Some new variables added to the musrSimAna - the documentation has not
     been updated yet.

$x$, $y$ and $z$). In such cases, the user can specify this in the field map
file using the keyword ``symmetryType \emph{number}'', where the \emph{number}
specifies how the field should be extrapolated to other octants.
The ``symmetryType 1'' case means that the planes of symmetry are (x,y) and
(x,z), i.e. if the field at point $(x,y,z)$ is $(F_x,F_y,F_z)$, the field in
different octants will look like this:
$(-x,y,z) \rightarrow (F_x,F_y,F_z)$;
$(x,-y,z) \rightarrow (F_x,-F_y,F_z)$;
$(-x,-y,z) \rightarrow (F_x,-F_y,F_z)$;
$(x,y,-z) \rightarrow (F_x,F_y,-F_z)$;
$(-x,y,-z) \rightarrow (F_x,F_y,-F_z)$;
$(x,-y,-z) \rightarrow (F_x,-F_y,-F_z)$;
$(-x,-y,-z) \rightarrow (F_x,-F_y,-F_z)$. \\
Similar case is the ``symmetryType 2'', where the planes of symmetry are
(x,y) and (y,z).
These two symmetry types are realised in a the spin rotator oriented along the z axis.\\
The ``symmetryType 1'' case can be used for a field between two electrodes
(e.g.\ of a spin rotator), where the electrodes are parallel with the $(y,z)$ plane
(i.e.\ the main component of the field is along the $x$ axis).
In this case: if the field at point $(x,y,z)$ is $(F_x,F_y,F_z)$, the field in
different octants will look be: \\
$(x,y,z) \rightarrow (F_x,F_y,F_z)$;\\
$(x,y,-z) \rightarrow (F_x,F_y,-F_z)$;\\
$(x,-y,z) \rightarrow (F_x,-F_y,F_z)$;\\
$(x,-y,-z) \rightarrow (F_x,-F_y,-F_z)$;\\
$(-x,y,z) \rightarrow (F_x,-F_y,-F_z)$;\\
$(-x,y,-z) \rightarrow (F_x,-F_y,F_z)$;\\
$(-x,-y,z) \rightarrow (F_x,F_y,-F_z)$;\\
$(-x,-y,-z) \rightarrow (F_x,F_y,F_z)$. \\
Similar case is the ``symmetryType 2'', where the main field component is along the
$y$ axis.
These two symmetry types are realised as electric and magnetic fields
in a spin rotator oriented along the z axis.\\
