Figure 9
The mirror leg drives are in closed-loop operation but no request for motion is issued. The position is held for 6 h while the absolute position encoders are sampled every second. (a) The vertical position is shown. The FWHM of the noise is 0.009 µm which is within the deadband of the closed loop showing the long-term position stability of the system. (b) The yaw angle is shown. The FWHM of the noise is 0.061 µrad which is within the deadband of the closed loop, showing the long-term angular stability of the system.
