[john rudy]

I think that baffling a Nobel prize winner is worth a round of applause (even if he was wrong).  Good going, Tony !!!

Charlie,
Please tell the person who pointed out the mistake in the active system 
that the figure is ok. The prominent seismometer is on stage 1 of the 
system. The other seismometers are mounted on the sides of stage 2 of the 
system to which the quad isolation stage is also attached.
Rainer
