Figure 16
(Left) Histograms of 100000 frames in the dark with different fine thresholds, for a single pixel. (Left inset) To centre the noise peak on approximately zero fine counts, the threshold at which 50% of frames give counts greater than zero is chosen, corresponding to a fine threshold of 1189. (Right) The means of the dark distribution for different fine thresholds (only those points shown in the residuals contributed to the linear fit). |
