So we found out that the ITMY vstop filter has been turned off. That's likely the cause of mysterious ring up of ITMY violin modes last night and tonight. I was able to damp the three highest modes (ITMY MODE2, MODE3, MODE5) with the settings on the table I confirmed on June 13. I haven't had a chance to re-comfirm all the settings. So until then I would either comment out IY violin mode damping guardian lines or just skip it for now.
Nevermind. I commented out every IY line except for MODE2, 3, and 5.

We tried the settings in the guardian (and in the new wiki) for ITMY mode 1 and mode 6, they worked so they are back in the guardian now. ETMX mode7 (507.195Hz) is the largest violin mode now, and I don't see settings for this mode on the wiki, so I tried FM1, FM4, and a +30 gain (BP, 100dB, 0 degrees of phase). This seemed to ring it up very slowly, so if we hadn't lost lock for unrelated reasons I would have tried a 60 degrees phase shift.
