Pedestal

Pedestal mean
Pedestal sigma
Pedestal for one event, channels 1 and 15, normal and switched

Pedestal mean

Pedestal mean (channels) vs time - each point is an average of 1000 events

Pedestal mean - 1450V - half ADC range (ch 4096 ~ 0.5V)

Just one event

Pedestal for one event

Pedestal for one event

Pedestal for one event - switched channels 1 and 15 between shaper and ADC

Pedestal for one event

This shows that switching ADC contributes about 100ch to the difference in pedestal.

One event, different preamps

To see if the largest and smallest pedestals are correlated with the shaper channels
