The last work that was done for the estimator was back on May 21st 84548. The data that I got then was of the Open Loop TFs for when SR3 OSEMINF gains were nominal (aka what they are now) vs our 'more calibrated' values that are shown in 84367. I then wrote a script that takes in the OLTF traces that were exported from diaggui and divides them for each DOF (results). The average between the two divided traces is what we are going to be using as the gain values needed to counter the 'more calibrated' values. I put these gains in as FM7(previously had old unused gains in) in the DAMP filter bank.

Today I changed the M1 coil driver state to 1, set the OSEMINF gains to the ones listed in 84367,  turned on FM7 for all degrees of freedom in the DAMP filter bank to turn on the gain corrections, changed the gain for DAMP Y to be -0.1 instead of the nominal -0.5, and then took SUSPOINT to M1 transfer function measurements.The measurements can be found in: /ligo/svncommon/SusSVN/sus/trunk/HLTS/H1/SR3/Common/Data/2025-06-24_1700_H1ISIHAM5_ST1_WhiteNoise_SR3SusPoint_{L,T,V,R,P,Y}_0p02to50Hz.xml, in svn as r12356.

After that, I took regular transfer functions with damping on for SR3 M1 to M1. Unfortunately I accidentally took the transfer functions for Pitch with the wrong bin width, so the original xml file there has double the values as the other ones. The saved .mat file, though, has the data all the same size. The measurements can be found in: /ligo/svncommon/SusSVN/sus/trunk/HLTS/H1/SR3/SAGM1/Data/2025-06-24_1900_H1SUSSR3_M1_WhiteNoise_{L,T,V,R,P,Y}_0p02to50Hz.xml, in svn as r12359. The results are found in: /ligo/svncommon/SusSVN/sus/trunk/HLTS/H1/SR3/SAGM1/Results/2025-06-24_1900_H1SUSSR3_M1_ALL_TFs.pdf, also r12359.

After these measurements, everything was put back to how it was before, including the OSEMINF gains, the DAMP Y gain, and the DAMP FM7 filters turned back off.
