... single pixel for 2 e − , a contiguous cluster of pixels for 3 e − and 4 e − ). A (1 e − , 2 e − , 3 e − , 4 e − ) pixel was defined to have a measured charge in the range ((0.63,1.63], (1.63,2.5], (2.5,3.5], (3.5,4.5]) e − , respectively. The number of 1 e − events in the data was corrected for misclassification using a Gaussian fit as shown in Fig. 16 (i.e., a few empty pixels would be measured to have a charge consistent with a 1 e − ...
