PTC with All Noises Combined

The new article in the PTC series by Albert Theuwissen shows all noise combined and then extracted back from PTC, demonstrating how a complete characterization can be done or, at least, fixed, non-temporal components. Here are the concluding remarks from the article:

In summary, the following data could be extracted from the measurements (the value put into the simulator are shown between brackets) :

- PRNU 3.2 % (3.0 %),
- total FPN on pixel level : 2.09 DN (2.07 DN),
- row FPN : 0.53 DN (0.48 DN),
- column FPN : 1.91 DN (1.92 DN),
- pixel contribution to FPN : 0.64 DN (0.48 DN),
- saturation pixel FPN : 135 DN (140 DN),
- saturation row FPN : 12.2 DN (11.1 DN),
- saturation column FPN : 12.3 DN (12.8 DN),
- onset anti-blooming : 1819 DN (1960 DN),
- saturation level : 2818 DN (2800 DN).
