BEGINRELEASENOTES

Defining a first draft for the muon system digitizer, which can do the following tasks:

  • Smearing the simHits in 2 Dimensions in the local coordinates of the chamber and applying the changes to the global coordinates of the Hits.
  • Emulating the efficiency of the chamber.
  • The generated root file will have branches to validate the smearing (Differences between DigiHits and SimHits in global coordinates).

Why not using MCRecoTrackerAssociation https://github.com/key4hep/EDM4hep/blob/main/edm4hep.yaml#L634 ?

Can it be used for linking between digi and sim? I fount it relates between reco and sim..
On another hand I'd like to see if there is an association also to store the validation data (e.g: simDigipPositionDifference)

// Detector efficiency
FloatProperty m_efficiency{this, "efficiency", 0.95, "Detector efficiency"};

// Declaration of validation distribution

Can you add a flag, set to false by default, to produce these collections? See e.g. https://github.com/key4hep/k4RecTracker/blob/master/DCHdigi/include/DCHsimpleDigitizerExtendedEdm.h#L78 (the branch will unfortunately still be there I am afraid)

DataHandle<podio::UserDataCollection<double>> m_simDigiDifferenceZ{"simDigiDifferenceZ", Gaudi::DataHandle::Writer, this}; // mm

// Random Number Service
IRndmGenSvc* m_randSvc;

@jmcarcell let us know if a consensus was reached on which random number generator we should use

// y resolution in mm
FloatProperty m_y_resolution{this, "yResolution", 1.0, "Spatial resolution in the y direction [mm]"};

// z resolution in mm

I don't understand why we need 3 numbers here. Since you do the smearing in local coordinates (as it should), 2 numbers should be sufficient no? OR at least we should put ine by default to 0, otherwise we really smear in the 3 dimensions.
