In preparation for conducting PI Q Measurements on the 13 kHz mode (IFO locking dependant) we added a 12 - 12.8 kHz & 12.8 - 13.8 kHz elliptical bandpass filters to H10MCPI_PI_DOWNCONV_DC8_INP [FM3, FM4], H1SUSETMYPI_ETMY_PI_DOWNCONC_DC7_INP [FM2, FM3] & H1SUSETMXPI_ETMX_PI_DOWNCONV_DC8_INP [FM1, FM2]. 12.8 - 13.8 kHz elliptical bandpass filters were also added to H1SUS_ETMSX_PI_UPCONV_UC8_SIG [FM6], H1SUS_ETMY_PI_UPCONV_UC7_SIG [FM3], H1SUS_ITMY_PI_UPCONV_UC8_SIG [FM5] & H1SUS_ITMX_PI_UPCONV_UC8_SIG [FM5].

In addition, to monitor the 13 kHz modes we added a cheby2 bandpass filter between 12.98 - 13.01 kHz to H1SUSPROCPI_PI_PROC_COMPUTE_MODE4_BP [FM2]. This should allow broad monitoring of the 13 kHz PI modes before each individual mode can be accurately determined. Additional broader filters may be needed.

Filter Parameters:
12 - 12.8 kHz - ellip("Bandpass", 4, 1, 40, 12000, 12800)
12.8 - 13.8 kHz - ellip("Bandpass", 4, 1, 40, 12800, 13800)
12.98 - 13.01 kHz - cheby2("Bandpass", 4, 40, 180, 200)

Unfortunately we never had time to conduct the measurements early this morning, but at least the filters are ready!
