[FDS] FDS noise - revisited

Greetings Borries:

I suspect that the oscillations will be speed independent.  There are other AOS parameters that may have more of an effect.  Tom, is there a settling time after the a movement, before the optical measurement?  Do we need to increase the settling time to lessen the effect of mechanical vibrations?
