Same network diagramms (single and double case) as in NET_DIAGRAMM,
where all links from the set {TGF+X} to itself have been removed.
However, all links from this set to {up/down} (and also inverse) have been kept.
(Of course also all links from {up/down} to {up/down} are kept.)

* 5 top nodes are visible in the file *.top (single and double case)
* Translation from short labels to full names and color codes of nodes
  are visible in the file *.info (single and double case)
* Here: top nodes for up/down are simple U1/U2, D1/D2 (single case) or U1(+/-), D1(+/-) (double case)
  (single: X9 + 2 up and 2 down nodes
   double: X9(+) + 1 up and 1 down with both (+),(-))

Color attribution for single case:
The TGF and X nodes have color of X9 (red).
For the other nodes there are two colors for up 
(green and olive) and two colors for down (blue and cyan) nodes.
For an up (or down) node the color choice is done by choosing 
the color of one of the two top nodes of the 
same group such that this node is a stronger follower for this 
corresponding top node (using the GrrplusGrq matrix).


Color attribution for double case:
The TGF and X nodes have color of X9(+) (red).
For the other nodes there are two colors for up 
(green for (-) and olive for (+)) and two colors for down 
(blue for (-) and cyan for (+)) nodes.
