Today we added the filter "resgain(0.2,2,20)" saved and loaded as "resG0.2" to the all type A IPs filter bank.
Let's try it in the noisy days and see what happens.
I profited of the bad wheather to test the performance of the resG.
In the attachet plots the results are shown:
-around 0.2 Hz the in loop sensors IP_DAMP_L/T shows some improvement (respect to the references spectra)
-sensors like BF_L/T and TM_OPLEV,with or without resgain at the IP stage, doesn't change to much.
After the test, I tried to lock the IFO several time, but the lock acquisition fails because of the saturation of FB mass actuation: I guess the TMs are still moving a lot because of the large amount of microseismic noise and just by adding a resG this issue can not be solved.
