Laser projection: Arcseconds and change in angular momentum (moments)

[jontelling]

This is mainly directed at the peachy team, but I thought I’d ask it (helping to build up a technical picture of the peachy).

Has the team done any tests to measure the oscillation frequency of the mirrors, if so what were your findings, IE when did you notice the laser path start to destabilize?
With the frequency of direction change (per mirror, each tested independently), say you picked one channel and you pulsed it at 10hz with an amplitude of 0.5arcsecond (or just the distance across the build level) when did you notice it was not really following the correct path?

I’m just picking numbers, feel free to substitute with realistic ones
Arcseconds, how fast can the mirror swing (really this should be a question of acceleration)

Seems my question was more or less answered here in another post.
