-/// \class AliMUONDigitCalibrator
-/// Class used to calibrate digits (either real or simulated ones).
-///
-/// The calibration consists of subtracting the pedestal
-/// and multiplying by a gain, so that
-/// Signal = (ADC-pedestal)*gain
-///
-/// Please note also that for the moment, if a digit lies on a dead channel
-/// we remove this digit from the list of digits.
-/// FIXME: this has to be revisited. By using the AliMUONDigit::fFlags we
-/// should in principle flag a digit as bad w/o removing it, but this
-/// then requires some changes in the cluster finder to deal with this extra
-/// information correctly (e.g. to set a quality for the cluster if it contains
-/// bad digits).
