This morning, I worked on balancing and floating the ITMX ISI. I also added some "temporary" masses (3kg) to the optical table to approximate the missing weight of the SUS fiber guards. As of now, the balancing is done, but I still need to go back in and fine-tune the lockers, then re-gap CPS's. Only issue I had was the LVEA seems seismically noisier than the end-station, which makes reading the floating position of the ISI on the CPS's difficult.
