digitize()

StatusCode MdtDigitizationTool::digitize ( const EventContext &  ctx, const TimedHits &  hitsToDigit, xAOD::MuonSimHitContainer *  sdoContainer  ) const

finaloverrideprotectedvirtual

Digitize the time ordered hits and write them to the digit format specific for the detector technology.

A new MuonSimHitContainer pointer is parsed to also create the MuonSDO. If a new SDO should be added to the container plese use the addSDO() method as defined below.

Fetch the needed conditions

Hit is masked in the database for whatever reason

Total tdc time is the sum of the drift time, the time of flight of the muon, the propgation along the wire and finally the constant t0 tube offset

Question: What happens if there're 2 digits such close by that their adc needs to be merged?

The HPTdc has 4 times higher clock frequency. Smear both

Put also in the twin tube digit

The signal for the twin tube needs to travel to the HV side & then through the complete twin tube

Total tdc time is the sum of the drift time, the time of flight of the muon, the propgation along the wire and finally the constant t0 tube offset

The digitization might have produced digits which are overlapping in time, in particular if twin tubes are hit. Filter tube digits which are produced within the dead time interval

Find the next digit which is either another tube or beyond the dead time

Write everything at the end into the final digit container
