So that I don't have to do loop compensation every time I measure a sensing matrix, I have put (back) in notches into FM10 of all the LSC filter banks, except MC2.
MICH already had this notch, PRCL and CARM both had it, although it was mislabeled in the filter title as "Notch410" rather than the truth, which is "Notch628".
The XARM and YARM filter banks were full, since we have not (in those filter banks) combined all of the resonant gains - 3.2Hz, 16Hz, 24Hz - into one module. I took out a CLP3000 ( cheby1('LowPass",2,3,3000)gain(1.41254) ) in each of those filter banks, and put in the notch.
I also have changed the band pass filters in the LSC-Lockin#_SIG filter banks to match this new drive frequency.
