Violin modes are high - new settings for ITMY08, ETMY01 and ETMY 20

Oli, Rahul

Given below are the latest settings for the run up violin modes, which looks to be working for this lock,

ETMY mode 01: FM1 + FM6 + FM10 gain -0.1

ETMY mode 20: FM1 + FM4 + FM10 Gain 1.0  (this mode was really rung up, so one should keep an eye on this one for the next few lock)

ITMY05/06 looks to be doing fine with the settings Oli/Tony found this morning.

ITMY 08: FM1 + FM2 + FM10 gain -0.1

None of the above settings are in the lscparams, we should try this tomorrow and check if they still work.
