Figure 5: Camera Gain Percentage may be source of variability in signal.

Figure 5:

The 27 true positive samples had camera gain percentage average of 15.9. The 8 false positive samples had camera gain percentage average of 48.5. Because of the few number of samples, we tested difference using Wilcoxon rank sum nonparametric (P=0.1604) which does not quite reach significance.
