Detailed Description

In the initialize() method, the PileUpMerge and StoreGate services are initialized, and a pointer to an instance of the class MuonDetectorManager is retrieved from the detector store and used to obtain a MdtIdHelper.The MdtDigitContainer is initialized and the simulation identifier helper retrieved, together with the pointer to the digitization tool. Random numbers are obtained in the code from a dedicated stream via AtRndmSvc, which is also initialized in the initialize() method.

In the execute() method, the digits and the SDOs (Simulation Data Object, container for simulation data to be preserved after the digitization procedue, and persistified together with the RDOs) containers are created and recorded on StoreGate; the MDTSimHit collection are merged using the TimedHitCollection sorted container (done in handleMDTSimHit(TimedHitPtr <MDTSimHit>& hit)) method); into a loop over the TimedHitCollection for the given DetectorElement, the handleMDTSimHit() method converts the SimID into the Offline ID to be associated to the Digit and pass to the digitization tool the drift radius and the distance to the chamber RO side (for the propagation delay computation). The digitization tool returns a drift time and an ADC count which are used together with the Offline ID, to create the digit object (in createDigits() method).

The finalize() method returns a SUCCESS StatusCode if the digitization procedure ends succesfully.
