keyword=check of front chamber demux
Mark Jones and I looked at the raw signals in the cable going into the level shifter for chamber 1 V2, M2 amd M3, which had bad demux spectra. For M3, recrimping the connector at the readout board appeared to improve the signal shapes / solve the problem. For M2, unplugging the LV power and pluggin it back in seemed to solve the problem. Huh. Maybe we just pushed a connector and removed some transient short, (other possible screwy electronics explanation of your choice) ...
Cosmic data to check these again would be nice. Since things loked good on a scope with the cover off, we left it half off.
