The figures below (for an N2 reference cell run) show a change in the structure of the S2 ADC signals since weekend running. There is a second peak at higher bin than the first, with a clear separation between the two (Fig. 1-3). This also shows up in the plots of the same signal without pedestal subtraction (Fig. 4-6).
I don't see structural differences in the other online plots.
