Back in July 2024 (LHO:78956, LHO:78960, LHO:78975), I'd installed some infrastructure in the h1iopomc0 front-end model that picks off the 4x copies of the 2x OMC DCPDs directly at the ADC input, sends them through a matrix, 
    H1:OMC-ADC_INMTRX_$m_$n
and pipes the matrix output into test filter banks, called 
    H1:OMC-DCPD_A1
    H1:OMC-DCPD_B1
    H1:OMC-DCPD_A2
    H1:OMC-DCPD_B2
As shown in the above mentioned aLOGs, these pick-offs are completely independent of the interferometer, the matrix output only goes to these four filter banks, and the filtered output is terminated in the front-end code. 
As such, there is no impact on the detector performance, noise, or calibration if and when the parameters of these pick-off paths are changed.
However, 
    - a lot of the noise investigations we'd like to do with these paths are the most interesting while the detector is in nominal low noise, the state we're in most often for observing
    - because this front-end is running at 524 kHz, 
         - storing these extra, test-only, filtered output channels to frames is too taxing on the data storage system, and
         - even *looking* at more than 3 channels at a time live is taxing on the front-end's given 1/(2^19 [Hz]) = 1.9 [usec] clock cycle turn-around time.
This makes the usual method of testing and changing parameters during an observing run -- "just change something during a lock-loss, during commissioning times, or during maintenance, then look at the data in the past" -- intractable.

So, all this being said, in order to increase the amount of live time we have to commission and iterate the tests done with this path, I've unmonitored all the EPICs records associated with these pick offs' input matrix and filters.
52 channels total, and the explicit list of unmonitored channels is attached as screenshots.

Details:
The h1iopomc0 model only has one SDF file in 
    /opt/rtcds/userapps/release/cds/h1/burtfiles/h1iopomc0/
        safe.snap
The target area's safe and OBSERVE .snap files that the front-end uses are both soft links to this file,
    /opt/rtcds/lho/h1/target/h1iopomc0/h1iopomc0epics/burt/
        OBSERVE.snap -> /opt/rtcds/userapps/release/cds/h1/burtfiles/h1iopomc0/safe.snap
        safe.snap -> /opt/rtcds/userapps/release/cds/h1/burtfiles/h1iopomc0/safe.snap
So. Using the graphical SPF interface, I unmonitored the channels as the graphical user inteface pointed to the safe.snap in the target area (which thus overwrites the real file in the userapps area), and then committed the file to svn rev r30313.
So, in order to increase the amount of NLN time we have
