Table 2: Summary of Run Trigger Rates
# Photoelectrons Triggered On	“No Source” Run Rate (Hz)	“Source” Run Rate (Hz)	“Shield” Run Rate (Hz)
2	16.9	16.9	16.9
3	16.9	16.9	16.9
4	16.1	16.6	16.4
5	12.4	15.3	14.5

The gain calculations to covert SiPM C's pulse area to photoelectrons may need to be tweaked slightly. The gain fit shown here was done with muons. However, it has been observed previously that SiPM C can be quite temperature-sensitive.

Updated Analysis (done on 2017/09/11)

Data was rounded to the nearest integer to replicate accessible simulation data. Muon data was also cut out to give a clearer image of signal
