For each beam pulse:

[math] ADC_{ave}^{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 {\sqrt{ \sum_{i=1}^{pulses}{ADC_{ave}^{pulse} - ADC_{ave}} }} 
                        { \sum_{i=1}^{16}{ADC_{i}}}; [/math]

Below is the plot of the charge in Faraday cup (pC) as a function of magnet current (vertical axis, A) (basically magnetic field) and ADC (horizontal axis).
