Figure 6
Comparison between per-ASIC and per-column per-ASIC offset correction. The value reported is the ratio between the standard deviation of corrected ADU values for the same dark run using the two methods. The vast majority of values are above 1, meaning that the per-ASIC correction generates more noisy data than per-column per-ASIC approach. (a) Comparison for CSPAD-140K (L730). (b) The same for a single CSPAD 2×1 module in the CSPAD-2.3M (L867). |
