I used the same fre swing data to diagnolize input matrices of following optics:
MC1, MC2, MC3

BS ETMX ETMY

AS1 AS4 SR2 PR2 PR3

For all these optics, the new input matrices worked well. Next step should be to take the local damping open loop transfer functions and standardize the loops to same UGF.

What didn't work:

• The calculated input matrix for ITMX differed from existing matrix too much, including overall sign of rows POS and PIT. Even after correcting those signs, I was not able to get a good damping loop configuration. So I have committed the new matrix to the repo but have not implement it. More close analysis or another test might be required for this optic.
• LO1, LO2, and ITMY were not analysed because their free swing test was not valid. LO1 and ITMY had non-working coils and LO2 was stuck during the test. We'll take another free swing test for these three optics (and possible ITMX) in near time.
