Anatoli question 1

To compare the performance between channels with high clock-noise pickup (10-15 DAC counts) and channels with low clock-noise pickup (3-5 DAC counts), will be convinient to plot superimposed the S-curves averaged over the good and bad channels, respectively. The same for the noise rate as a function of the threshold value.

Figures 1 and 2 show the threshold scan averaged for good and bad channels for $0$ and $2$ fC of input charge, respectively. Figures 3 and 4 shows the same plots in logarithmic scale. Figures 5, 6, 7 and 8 show the rate as a function of the threshold value for 0, 2, 3 and 4 fC of input charge, respectively. Figures 9, 10, 11 and 12 show the same plots in logarithmic scale.
Note: The test setup is the same as in the 3 stack test bench studies i.e. no cooling plate and module attached, what could modulate the amplitude of the clock pickup.
