Measurements done on IMs with damping loops turned off, and step functions put into the test alignment offsets in pitch and yaw.

Yaw shows yaw peaks.

Pitch shows pitch peaks, and yaw peaks when yaw is given a step function.

I could not locate historical Q measurements for pitch and yaw, only length, bounce, and roll.

For completeness, I've included resonant frequancy measurements from LHO and LLO.
