Hence my hypothesis that the sensor is warmer causing more dark current and thus more dark current noise. The numbers match very well. The additional noise is almost exactly what you'd expect if the extra offset was due to dark current.

We're dancing on the edge of that dichotomy between HW and SW engineers and I only get paid for that in my day job so I'll shut up now
