ChamberIdMap

using Muon::MuonTruthSegmentCreationAlg::ChamberIdMap = std::map<Muon::MuonStationIndex::ChIndex, std::vector<Identifier> >

This map contains all the hits corresponding to truth muons classified by chamber layer that recorded them.

ChIndex is the chamber layer index (e.g. BMS, BOL,...), while Identifier is the hit ID, which represents the channel where the hit has been recorded.

This function performs, for each truth muon, the actual segment creation and stores segments into a new container

Parameters

segmentContainer.	Firstly, we retrieve simulation data from m_SDO_TruthNames and copy it into a new vector, keeping only the data corresponding to the correct detector technologies. Then, we loop over chamber layers and over the corresponding hit IDs, both provided by
ids,and	we store: *- gas-gap for hits with a phi measurement -> phiLayers *- gas-gap for hits recorded by MM or CSC -> precLayers *- 10*multi-layer + tube_layer for hits recorded by MDT -> precLayers *- gas-gap for hits recorded by trigger chambers without phi measurement -> etaLayers Then, in the same loop over hit IDs, we retrieve simulation data for that hit, specifically the global position, needed to retrieve for each chamber layer the pair of hits with the largest distance. If a pair of hits is found and at least three precision measurements are available, we proceed with the truth segment creation. We create a segment obj and we fill it with number and type (see above) of hits available, the
truthLink	link to the corresponding truth muon, and the position and direction of the truth segment, calculated with hit pair global positions. Finally, we append the sector, chamber layer, station eta, and technology of the chamber where the segment was recorded.
ctx	tells us in which event we are
truthLink	link to the corresponding truth muons
ids	chamberIdMap storing truth hit IDs classified by chamber layer
segmentContainer	segment container
