Corrected ApplyResponseToTrackerDigit():
- the de-calibration is applied on the physics signal (then at
digit::Signal() )
- noise is independent of the gain. (It is a constant in the dynamics range
of the electronics. Indeed, pedestal data is the results from the FEE and
gain is been already taken account. Then the noise need simply to be added
to digit::signal/gainMean.
- pedestal is added after.
Then acd=(signal/gainMean) + adcNoise + pedestal if we have a physic signal
and adc=adcNoise+Pedestal if it is a noisy pads.
