With Dave's help we installed all of the front-end model changes described in LHO:76850, and I've followed up behind the model changes with upgrades to the MEDM screens to show the new infrastructure -- then filled in the infrastructure with EPICs values, settings, and filters.

So, as of now,
    - As with the rest of the BSC Quads, Triples, Doubles, and HAM Triples, the the HAM doubles and single suspensions now are ll using a fully functional, sensible BLRMS system, calibrated into microns_RMS.
    - The thresholds have been generically set to 150 [um_RMS] for starters, since we have little history of understanding how the SUS behave in this 0.1 to 10 Hz band in a physically meaningful way. Please tune as you see fit if it's troublesome at this starting value.
    - The OMC ASC that's fed to the OMC SUS is now routed through the SUS-OMC_M1_LOCK_[LPY] bank, now has proper 2k to 16k AI filtering in all of those DOFs, and the LOCK_[LPY] output goes through the DRIVEALIGN matrix.
    - However, in an effort to make the least changes to the existing functionality, I've turned OFF the P2L and Y2L gains that were in place but not used for the time being. Will commission the drivealign gains again later, but for now the OSC ASC path should behave exactly as it had before, just with a proper 2k to 16kHz AI filter that should not impact the control stability.
    - The channels that are stored in the frames that record the history of the control signal have changed 
        from H1:SUS-OMC_M1_ASC_[LTVRPY]_IN1_DQ
        to H1:SUS-OMC_M1_LOCK_[LPY]_IN1_DQ
        which includes H1:SUS-OMC_M1_ASC_[PY]_IN1_DQ which were (for some reason) 
        in the GDS Broadcaster frame list, so they should now be mapped one-to-one to 
        H1:SUS-OMC_M1_LOCK_[PY]_IN1_DQ. 
      @DetChar -- Maybe these were used in the summary pages or something? 
    - All model, MEDM, and filter changes have been committed to the userapps repo.
    - All new EPICs settings have been save in every impacted SUS's SDF system.

More details to come tomorrow.
