The coincidence for counters six and seven was measure once for about ten minutes. The frequency was 654 counts/minute which is what the counts per minute for the coincidence of counters six, seven, and eight was divided by.
This performance study shows the desired distribution, Gaussian-shaped. The highest number of pulses occurs around 10 nanoseconds as it should. The study was run with the counter set to 0.998 volts.
