16 kHz versions of A1, B1, A2, B2 OMC DCPD Channels Installed and Functional

This morning, Dave installed the model changes I prepped yesterday (LHO:82479), that installs front-end infrastructure to downsample the output of the OMC DCPD 524 kHz test banks (originally installed in July 2024 LHO:78956), in light of all the flurry of data analysis, and it revealing confusing results in the last two weeks (LHO:82420 and LHO:82294).

These model changes have been committed to the userapps svn repo under
    /opt/rtcds/userapps/release/
        cds/h1/models/h1iopomc0.mdl   rev 30549
        omc/h1/models/h1omc.mdl       rev 30548
        omc/common/models/omc.mdl     rev 30547

Post-install, I built up MEDM screens. For now and for better or worse, all the screens are committed in the same location, 
    /opt/rtcds/userapps/release/cds/h1/medm/     
        Overview screen:
        H1OMC_DCPD_TEST_OVERVIEW.adl   
            Subordinate screens linked from overview:
            H1IOPOMC0_524KHZ_ADC0_INMTRX.adl
            H1IOPOMC0_524KHZ_DCPD_FILTERS.adl
            H1OMC_16KHZ_DCPD_FILTERS.adl
            H1OMC_DCPD_BALANCE_MATRIX_OVERVIEW.adl
            H1OMC_16KHZ_DCPD_SUMNULL_FILTERS.adl

Because the model changes came with a channel name change for the 524 kHz test filter path,
     H1:OMC-DCPD_A1   >>    H1:OMC-DCPD_524K_A1
     H1:OMC-DCPD_B1   >>    H1:OMC-DCPD_524K_A2
     H1:OMC-DCPD_A1   >>    H1:OMC-DCPD_524K_B1
     H1:OMC-DCPD_B2   >>    H1:OMC-DCPD_524K_B2
I needed to re-install all the filtering in the foton file, so I grabbed all the filters shown in LHO:82384 from 
    /opt/rtcds/lho/h1/chans/filter_archive/h1iopomc
        H1IOPOMC0_1421610658.txt
and pushed them to the cited version of the userapps svn 
    /opt/rtcds/userapps/release/cds/h1/filterfiles/H1IOPOMC0.txt   rev 30556

Finally, I set all of the EPICs records to how they're shown in the attached MEDM screen shots, accepted and unmonitored everything in the following SDF save files, and committed the fies to svn:
h1iopomc0 model's safe and OBSERVE files are linked to the same file,
        /opt/rtcds/userapps/release/cds/h1/burtfiles/h1iopomc0/safe.snap.      rev 30557

    h1omc model's safe and OBSERVE files are linked to 
        /opt/rtcds/lho/h1/target/h1omc/h1omcepics/burt/OBSERVE.snap -> /opt/rtcds/userapps/release/omc/h1/burtfiles/h1omc_OBSERVE.snap      rev 30558 
        /opt/rtcds/lho/h1/target/h1omc/h1omcepics/burt/safe.snap -> /opt/rtcds/userapps/release/omc/h1/burtfiles/h1omc_down.snap       rev 30558 

We're now in observing, and Corey had to make no adjustments to the OMCs SDF save file.

OK! That's all the pipe laying and masonry work -- now on the the science of looking at the differences between these channels!!
