This is my final SISO Wiener filter for MCL that uses the T240-X seismo as its witness.
The main difference between this filter and the one on elog:11532 is the actual 1/f rolloff this filter pocesses. My last filter had a pair of complex zeroes at 2kHz, that gave the filter some unusual behavior at high frequencies, thanks Vectfit. This filter has 10 poles and 8 zeroes, something Vectfit doesn't allow for and needs to be done manually.
The nice thing about this filter is the fact that Eric and I turned this filter on during his 40 min PRFPMI lock last night, Spectra for this is coming soon.
This filter lives on the static Wiener path on the OAF machine, MCL to MC2, filter bank 7.
Anyways, the usual plots are shown below.
