Ch 3 looks fine, as do ch4 V's, but ch 4 u's have a problem in the demux and in some high number wire groups. In the past, when the readout cables made poor contact, there seemed to be a ~capacitively coupled / differentiated signal that led to a peak in the demux spectrum at about 15 ns width. I do not recall if the wiremap also looked funny for those channels.
So... sometime later today we should have an access and make sure there is good contact for the ch 4 u cables coming out of the chamber, and at the level shifters...
