Prep for more LSC, ASC, SQZ, OMC Rack Power Supply Work -- Offloaded MC WFS, Saved SUS MC OPTICALIGN Alignment Slider Values and PSL Input PZT Steering Slider Values in SDF
J. Kissel, T. Shaffer In order to aide recovery later today post round two of changing out the power supplies for the ISC racks (WP 11193, LHO:69652, LHO:69631), TJ and I offloaded the MC WFS to their suspension's alignment and input PZT sliders (while the IMC is locked, use IMC_LOCK guardian, request MCWFS_OFFLOADED). Then, to make sure it sticks across computer reboots, we accepted them in each computer's safe.snap SDF file. - Because alignment sliders are not monitored in SUS SDF systems, for the IMC SUS, MC1, MC2, and MC3, this means changing the SDF view to FULL_TABLE, and accepting OPTICALIGN*OFFSET values, - for the input PZTs, which live in the h1ascimc front-end model, we merely accepted them in the SETTINGS_DIFFS list, because these *are* monitored. Neither SUS nor PZTs offset changes were that large, but it'll help.
