These plots are made by two scripts launched from the OPS -> WEEKLIES screen (BSC CPS PYTHON & HAM CPS PYTHON), unfortunately they only work from the Debian machines (the Ubuntu signal python libraries don't have Welch!? ). The message Ed posted comes from some warnings that the scripts post to the xterm launcher window. If operators use these scripts to do the CPS famis, they should include that output, if any this comes up.

For this task, corrective action is generally only required when either 1.) a single sensor is close to a factor of 10 above the CPS spec noise around 100 hz (I haven't added the noise spec to the plots yet, coming soon), or  2.) multiple sensors on a stage are a factor of a few above the spec noise. This is usually not urgent (exceptions being the HAM5 incident in December, the ISI wouldn't re-isolate), and can wait to be addressed on a maintenance day.
