Current version of pedestals evaluation
pedestals_L = pedestals_H(M) - <offset-difference-H(M)-L>
Questions
- do we need to account in the difference between offset and pedestal (Gabriel's version)
- the same difference may be between B(L) and pedestal_(L) or it is smaller due to the gain?
- is current procedure correct?
- if not
- what is correct procedure?
- or what could we calibrate with charge injection?
