Detailed Description

Replacement for TrackingTruthProducer in the new pileup mixing setup.

The configuration parameters are:

Parameter name Type Description
volumeRadius double The volume radius in cm used if ignoreTracksOutsideVolume is true.
volumeZ double The volume z in cm used if ignoreTracksOutsideVolume is true.
ignoreTracksOutsideVolume bool If true, sim tracks that have a production vertex outside the volume specified by volumeRadius and volumeZ won't be turned into TrackingParticles. Doesn't make much difference to be honest, over a huge range of volume sizes so there must be a cut earlier in the simulation.
maximumPreviousBunchCrossing unsigned int Bunch crossings before this number (inclusive; use positive integer) won't be included. Setting to zero means only in-time.
maximumSubsequentBunchCrossing unsigned int Bunch crossings after this won't create any TrackingParticles.
createUnmergedCollection bool Whether to create the TrackingParticle collection without bremsstrahlung merged.
createMergedBremsstrahlung bool Whether to create the TrackingParticle collection with bremsstrahlung merged. At least one of createUnmergedCollection or createMergedBremsstrahlung should be true otherwise nothing will be produced.
createInitialVertexCollection bool Whether to create a collection of just the initial vertices. You can usually get this information from one of the other collections (merged or unmerged bremsstrahlung), but for this collection no selection is applied. Hence you will always have all of the initial vertices regardless of how tightly you select TrackingParticles with the "select" parameter. Note that the collection will have no links to the products of these vertices. If you want to know what came off these vertices you will have to look in one of the other collections. The name of the collection will be "InitialVertices".
alwaysAddAncestors bool If a sim track passes selection and is turned into a TrackingParticle, all of it's parents will also be created even if they fail the selection. This was the default behaviour for the old TrackingParticleProducer.
removeDeadModules bool Hasn't been implemented yet (as of 22/May/2013).
simTrackCollection edm::InputTag The input SimTrack collection
simVertexCollection edm::InputTag The input SimVerted collection
simHitCollections edm::ParameterSet A ParameterSet of vectors of InputTags that are the input PSimHits
genParticleCollection edm::InputTag The input reco::GenParticle collection. Note that there's a difference between reco::GenParticle and HepMC::GenParticle; the old TrackingTruthProducer used to use HepMC::GenParticle.
allowDifferentSimHitProcesses bool Should be false for FullSim and true for FastSim. There's more documentation in the code if you're really interested.
select edm::ParameterSet A ParameterSet used to configure a TrackingParticleSelector. If the TrackingParticle doesn't pass this selector then it's not added to the output.

const bool TrackingTruthAccumulator::addAncestors_

bool TrackingTruthAccumulator::allowDifferentProcessTypeForDifferentDetectors_
private

When counting hits, allows hits in different detectors to have a different process type.

Fast sim PSimHits seem to have a peculiarity where the process type (as reported by PSimHit::processType()) is different for the tracker than the muons. When counting how many hits there are, the code usually only counts the number of hits that have the same process type as the first hit. Setting this to true will also count hits that have the same process type as the first hit in the second detector.

bool TrackingTruthAccumulator::chargedOnly_

Uses the same config as selector_, but can be used to drop out early since selector_ requires the TrackingParticle to be created first.

const unsigned int TrackingTruthAccumulator::maximumPreviousBunchCrossing_
private

The maximum bunch crossing BEFORE the signal crossing to create TrackinParticles for. Use positive values. If set to zero no previous bunches are added and only in-time, signal and after bunches (defined by maximumSubsequentBunchCrossing_) are used.

const unsigned int TrackingTruthAccumulator::maximumSubsequentBunchCrossing_
private

The maximum bunch crossing AFTER the signal crossing to create TrackinParticles for. E.g. if set to zero only uses the signal and in time pileup (and previous bunches defined by the maximumPreviousBunchCrossing_ parameter).
