keyword=Displacement in BB Total Sum ped_sub ADCs
There seems to be a slight systematic displacement in the BB Total Sum ped_sub ADCs, shifting the shape by about 100 channels toward higher ADC values. All the TSum ADCs seem to show this behavior (Fig. 1); I've zoomed in a little on the top 3 graphs so that it shows up a little better.
Any thoughts? The golden run is 1533, from yesterday; the target polarization was longitudinal then and is transverse now. Would that explain this behavior?
