BSC2 CPS issues...resolved?
A few weeks ago, Vincent reported some of BSC2's St2 cps-es were "weird". With no changes to the system, some were reading ~ +/-15000 cts. Today, in preparation for fixing the system, Vincent and I checked the sensors again and they were back to normal. Grounding issues are suspected, and a better connection to ground was added this afternoon. Hopefully, the sensors are now fixed, but power spectra still show some noise in some of the sensors. Vincent will be taking TF's over the weekend, in preparation for the impending BS glass install.
