This aLOG that summarizes all the details of the work that went in to upgrading the SUS ETM and SUS TMS watchdog systems this past Tuesday, Mar 12 2024.

Front-end model and MEDM screen infrastructure changes: LHO:76269
    To receive these upgrades, 
    - svn up the following common directories,
        ${userapps}/release/sus/common/models/
        ${userapps}/release/sus/common/medm/quad/
    - svn up the following h1 specific directories and copy what top-level changes that are shown in the above linked aLOG,
        ${userapps}/release/sus/h1/models/
        ${userapps}/release/sus/h1/filterfiles/
        
Dave's summary of the install, and corresponding issues: LHO:76304

Filling out the foton and EPICs infrastructure to get the new WD system functional: LHO:76352
    To receive these upgrades,
    - svn up the following h1 specific directories and copy what filters you see in the OSEMAC_BANDLIM and OSEMAC_RMSLP filter banks
        ${userapps}/release/sus/h1/filterfiles/
      or use the design strings described in LHO:76352.
     
A review of the calibrated BLRMS output vs. thresholds: For ETMs LHO:76343 for TMTS LHO:76347
     - Note, 25 [um_RMS] is still an arbitrary threshold. We've already found that it might behoove us to increase the ETM L2 threshold to 30 [um_RMS], but for many other stages, something lower might suffice. Only time and data will tell.

Surrounding python code underneath MEDM infrastructure: LHO:76389.
    To receive these upgrades (when we've reconciled the issues discussed in this LHO:76389 aLOG)
     - svn up the following common directory,
        ${userapps}/release/sus/common/scripts/

Proposed Schedule of the continued roll-out:
Next week (Mar 19 2024), we hope to upgrade the ITMs and the BS.
The following week (Mar 26 2024), we hope to upgrade the HSTS and HLTS.
The following week (Apr 02 2024), we hope to upgrade the OMCS, HTTS, and HAUX
The following week (Apr 09 2024), we hope to go through the already new WDs and calibrate their RMS signals, and update the thresholds, like we'll have done for the above "older" suspensions along the way.
