I kept getting a bunch of spikes in the upper end of the waveforms when correcting. Tried swapping corrector boards and DCSB analog boards AN2 and AN4 but could not get rid of the spikes nor the pegged corrector table (light). In cirrus now so I will regroup and try again next clear opportunity. May try putting height mask in with taped slots 1 and 3 to check if detectors are really aligned up/down as assumed.
