Pedestal values are removed because they are added by certain camera control programs and are not part of the real data.
If not properly accounted for in the data reduction, incorrect image calibration can result.

Does this removal cause a problem for your purposes?

Ahh thank you.

Hasn't caused a problem, I had just noticed it in the log and wasn't sure why it was being removed.

I can see now the pedestal value stored in the header for the camera. Thanks for the clarification!
