Kiwamu, Lisa

We monitored the intensity noise coupling to DARM over more than 2 hours during one of the long lock tonight by injecting noise in the ISS outerloop excitation point.

Labels correspond to local times (September 16).

The coupling changes significantly over time. Kiwamu tried to reduce the CO2 ITMX power to see if we could maintain a low coupling, but that didn't really work.

After a couple of hours we could clearly see the coupling getting significantly worse (red trace).
