SQZ has been acting up today. It seems like the high frequency squeezing is bad, and our range is only 140MPc.

The first try per the wiki is to change the sqz angle, which was done but did not improve the squeezing. Next, I went for the temperature. However, upon running the SQZ_OPO temp scanning guardian, the FC unlocked and wouldn't relock.

I reset the values again for ZM3, FC1 and FC2 P and Y and got pack to observing but still with terrible range. Then, assuming that the FC unlock was a fluke or that it was related to the bad squeezing, I ran the opo scan guardian again. Same thing happened and I had to reset the values again.

Technically, the opo temperature has not actually been changed. If LLO drops out, I will attempt to go to commissioning to adjust manually.
