DigitContainers are sorted by DigitCollections which are the ensemble of all hits in a given MuonChamber.

To fill the final DigitContainer thread-safely, the DigitCollections shall be cached pre cached in a OutDigitCache_t vector which is later moved to the final DigitContainer

Adds the timed simHit to the output SDO container.

The hit may be rejected if it's originating from pile-up and the pile-up truth skimming strategy is applied

digitize()

StatusCode MuonR4::MmFastDigiTool::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 conditions for efficiency calculations

ignore radiation for now

Calculate the index for the global hit counter

Pipe some dummy values to the digit to ensure that the pdo / tdo calibration does not reject any hit downstream. Or in other words how much do you want... All charge

We're using the NSW uncertainty DB to smear the truth-hit positions using the best known uncertainties. In the process of digit -> RDO -> PRD, the smeared hit position is gonna be lost However, recall that the simplest way to generate a MM prd from RAW hits is the clustering by means of center of gravity. On average, a muon passage makes 3-4 strips fire. Assuming 3 strips, the smeared position can be written as

        x = w_{1}*(c - p) + w_{2}*c + w_{3}*(c + p),

where c is the strip centre, p the pitch and w_{i} are the induced charge fractions on each strip

      1 =  w_{1} + w_{2} + w_{3}

      x = (w_{1} + w_{2} + w_{3}) * c + (w_{3} - w_{1})*p 

--> x = c + (w_{3} - w_{1}) *p --> (x-c) / p = (w_{3} - w_{1})
--> (x-c) / p + w_{1} = w_{3}

1 = 2 * w_{1} + w_{2} + (x-c) / p 1 - (x-c) /p - 2*w_{1} = w_{2}

0< w_{1} < 0.5 - (x-c) / 2p

Write everything at the end into the final digit container
