Hi Jens,
Ok. I think I'm on to something here ...
The read noise is high: about 280 e rms. At saturation, the noise is
750 e rms. This is only about 2.7 times the read noise. So, I surmise
I'm not actually ever reaching the shot-noise limited region!
What threw me was that I was able to fit (with low residual error) a
line to a major portion of the curve, which I assumed to be the
shot-noise limited region. I no longer believe this is the case.
However, I still have high dynamic range: saturation = 500ke. So
dynamic range is 20*log(500000/280) = 65dB. Is it strange that I can
have both high dynamic range and high read noise? I know the two are
somewhat decoupled, because the full well is quite high, but something
seems a little off here.
Best regards,
Patrick
