BSC-ISI CPS Noise Spectra
Spent some time looking at the noise of the CPS on the BSC after rerouting the sync signals
One figure is a matlab plot of some calibrated signals using a fixed target on which there are some VERY bad BS channels
the second plot is a dtt screen of all of the BSC CPS channels in counts, (BS-V3 is looking at a fixed target, all other channels are looking at motion) with all of the ISIs OFF.
there are a number of icky channels

Phil rewired the CPS distribution box ( i think that it is now identical to what is at LLO) and the really horrible noisey channels got better
there is still some excess noise in ITMY stage 2 corner three and may itmx stage 1 H3 although that might not be real
