For each beam pulse:

[math] ADC_{avg}^{pulse}=\frac{\sum_{i=1}^{16}{ADC_{i}*i}}{\sum_{i=1}^{16}{ADC_{i}}};[/math]

For distribution over all beam pulses:

[math] ADC_{ave}=\frac{\sum_{i=1}^{pulses}{ADC_{avg}^{pulse}}}{pulses};[/math]
[math] ADC_{sigma}={ \sqrt{\frac{1}{pulses}\sum_{i=1}^{pulses}{\left(ADC_{avg}^{pulse} - ADC_{avg}\right)^{2}}}};[/math]

Here is:
1. ADC# = bridge#
2. Pulse# = ReadOut# = Entry# = Event#

Some examples of ADC mean value distribution. Here are:
1. x axis: ADC mean value for one pulse
2. y axis: number of pulse w/ that ADC mean value
