Similarly as in llo (ref llo alog 69495), a comparison of the cps blrms channels vs spectra is attached for the bsc and hams. This is to confirm we can use those channels for automated cps noise monitoring in guardian.

Same observations as for LLO :

1- the blrms channels are all working
2- the threshold of 30nm rms seems like a good number to start with for guardian monitoring
3- some odd behavior on some channels - eg itmy stage 1 - 65_100Hz (p5) where, looking at the spectra, we would expect the v2/green channel to be the highest in the blrms signal. Nathan has some ideas of how to verify this, see alog 69603.

Next step : copy the CPS_NOISEMON state from the LLO DIAG_MAIN to the corresponding LHO guardian
