We injected vibration to the PSL optical table(near the periscope of the exiting point)

When we injected 80Hz vibration, the signals appeared in the IMMT TRANS QPDs and ISS outloop PD, CARM control signal and DARM control signal.

That imply laser beam have jitter if there is origin of the vibration on the optical table.

Next, we will write the noise curce for laser.
