I found that none of the filter banks in the LSC input signals have the precise anti-whitening filters.
I installed the precise filters on REFL11, REFL33, REFL55 and AS55 based on Jenne's measurement (#4955)
After installing them I briefly checked the REFL11 sensing matrix with the PRMI locked, but it didn't change so much from what I got (#6283).
But I felt that the PRMI became more robust after that ... I just felt so ...
