The peaks remained in squeezing spectrum after the installation of new FI
The attached figure shows the remained peaks in the squeezing/anti-squeezing spectrum.
In the anti-squeezing spectrum, we could see that all the peaks appear at a harmonics of 50Hz.
In the squeezing spectrum, the peaks appear mainly at harmonics of 50Hz. Only 3 out of 14 peaks are not harmonics of 50Hz but they are close.
