KVGroupReconstructor Class Reference

Detailed Description

Base class for particle reconstruction in one group of a detector array.

KVGroupReconstructor is the basic working unit of event reconstruction. A KVEventReconstructor will use many KVGroupReconstructor objects in order to reconstruct an event from data detected by the array (let us recall that a group of detectors is the largest part of any array which can be treated independently of all other detectors).

Daughter classes of KVGroupReconstructor can be specialised for event reconstruction in specific arrays (or even specific parts of specific arrays).

Member Function Documentation

AnalyseParticles()

void KVGroupReconstructor::AnalyseParticles

(

)

Analyse and set status of reconstructed particles in group, to decide whether they can be identified and further treated straight away.

If there is more than one reconstructed particle in the group on different trajectories which have a detector in common, then it may be necessary to identify one of the particles before the others in order to try to subtract its contribution from the common detector and allow the identification of the other particles.

Definition at line 334 of file KVGroupReconstructor.cpp.

Calibrate()

void KVGroupReconstructor::Calibrate

(

)

Calculate and set energies of all Z-identified but uncalibrated particles in event.

Clear()

void KVGroupReconstructor::Clear ( Option_t *  = "" )

inlineoverridevirtual

Factory()

KVGroupReconstructor * KVGroupReconstructor::Factory ( const TString &  plugin = "", const KVGroup *  g = nullptr  )

static

Create a new object of a class derived from KVGroupReconstructor defined by a plugin

If plugin="" this is just a new KVGroupReconstructor instance

Reconstruction can be activated or deactivated selectively depending on the group using .kvrootrc variables:

Deactivate reconstruction for all groups in [array]:

[dataset].EventReconstruction.[array].DoReconstruction: no

Activate reconstruction only for given group numbers:

[dataset].EventReconstruction.[array].DoReconstruction.OnlyGroups: 1,13,356,2,33

GetNUnidentifiedInGroup()

Int_t KVGroupReconstructor::GetNUnidentifiedInGroup ( )

inline

number of unidentified particles reconstructed in group

Definition at line 133 of file KVGroupReconstructor.h.

Identify()

void KVGroupReconstructor::Identify ( )

virtual

Identify all particles reconstructed so far in this group which may be identified independently of all other particles in the group according to the 1st order coherency analysis (see AnalyseParticles() ). This is done by calling the method IdentifyParticle() for each particle in turn.

Particles stopping in the first member of a telescope will have their Z estimated from the energy loss in the detector (if calibrated): in this case the Z is a minimum value.

Reimplemented in KVINDRAGroupReconstructor.

Definition at line 565 of file KVGroupReconstructor.cpp.

Process()

void KVGroupReconstructor::Process

(

)

Perform full reconstruction of particles detected in group.

This will call in order Reconstruct(), Identify(), Calibrate() and AddCoherencyParticles()

• identification can be inhibited (for all groups) by calling KVGroupReconstructor::SetDoIdentification(false);
• calibration can be inhibited (for all groups) by calling KVGroupReconstructor::SetDoCalibration(false);

Definition at line 134 of file KVGroupReconstructor.cpp.

Reconstruct()

void KVGroupReconstructor::Reconstruct ( )

virtual

Reconstruct the particles in the group from hit trajectories

We work our way along each trajectory, starting from the furthest detector from the target, and start reconstruction of a new detected particle depending on decision made in ReconstructTrajectory() for each detector we try (normally just the first fired detector we find).

The reconstruction is then handled by ReconstructParticle().

Reimplemented in KVINDRAFilterGroupReconstructor.
