void MuonR4::TruthSegmentMaker::buildSegmentsFromBkg ( const EventContext &  ctx, const Amg::Transform3D &  locToGlob, const SimHitVec_t &  simHits, WriteDecorHolder &  writeShip  ) const

private

Attempts to assemble truth segments from a list of loose sim hits, i.e., the hits are stemming from a muon but due to the pile-up truth record, no HepMCParticles are recorded.

Hits are paired based on kinetic energy, and line compatibility

Parameters

ctx	EventContext to access the uncertainty conditions data during segment building
locToGlob	Transform from the sector -> global frame
simHits	Collection of all sim hits in the sector without truth link
writeShip	Helper struct carrying the output segment container & the associated decorators

Closest beam spot approach

First compare the energies

Calculate the approach to the cylinder

private

Takes a list of related sim hits and transforms them into a truth segment.

If there're less than 3 precision hits, then no segment is created.

Parameters

ctx	EventContext to fetch the hit uncertainties from store gate
locToGlob	Coordinate transform from sector frame -> global frame
hits	List of hits to be combined onto a single segment
writeShip	Helper struct carrying the output segment container & the associated decorators

Find the hit which is closest to the refernce plane to express the segment at the centre plane

Express the simulated hit in the center of the chamber

Associate the hits to the segment and calculate the expected hits
