I noticed that the Range started to drop, and the guardians had some things to tell me.

I followed those instructions in the guardian messages and requested RESET_SQZ_ASC_FDS[97]

Immediatley, ZM4 Started to Saturate and wouldn't stop even if I took SQZ_MAN to down.
I eventually took ZM4 to Damped for a few minutes while I try to find a solution.

One of the solutions I tried were to "Gracefully clear the SQZ-ASC offsets.

Eventually I figured out that ZM4 slider needed to be moved in pitch since it had drifted off quite far.
I got SQZ_MAN back to  FREQ_DEP_SQZ to see if that ZM4 move made a difference.

It did not..... then I requested a SCAN_ALIGNMENT_FDS to see if that would help.

I then took a Low range Coherence plot and a comparision plot from before the range fell in this lock and after.

Then I adjusted the OPO Temp and then requested SCAN_ALIGNMENT FDS again.
I was only able to get the range back up to 138 Mpc.
