Transfer function measurement of ETMY MNL to DARM

I measured the trasfer function from MNL to DARM by using ETMY.
Figure 1 shows the result.
The data was stored at /users/Commissioning/data/NoiseBudget/TFs/2022/1005/TF_MNLtoDARM_221005.xml

According to the eigenmode list (JGW-G1807866-v1), there are several candidate of the resonances that can be seen at 22 Hz and 43 Hz.
I don't have enough time to identify the resonant modes but these would be reduced by decoupling the actuators, hopefully.
This TFs are consistent with TFs measured with ALS_DARM around 10 Hz (klog21689).

Noise projection to DARM from MN_DAMP_L will be calculated soon.
