Current version of L-pedestals evaluation
...
- pL = pH - (BH-BL)
Possible correction for difference between B and p
- pL = pH - (BH-BL) + (BH-pH)*GL/GH,
where
- p - pedestal
- B - fit base-level parameter
- G - gain
Questions
- do we need to account for the difference between offset (B) and pedestal (Gabriel's version)
- the same difference may be between fit 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?
