Figure 5
The normalized residual signal with different exposure times was averaged and plotted against the number of reads on the detector. The decay of the normalized signal in the dark frames of various data sets (with different exposure times) is found to follow a general trend as shown by the solid line in the figure, and they are within the error bar provided. The signal drops to 2% of its initial value at the second read and to 0.4% at the third read. |
