Detailed Description

This algorithm is very basic, there is no attempt to deal with ambiguities, such as noise etc. The GEMCSC track segment is built starting from a CSC segment and trying to match GEM rechits. The GEM rechits are searched inside a conigurable (eta,phi) window and associated to the segment. This collection of GEM rechits and CSC semgent is called the GEMCSC Ensemble.

std::vector< GEMCSCSegment > GEMCSCSegAlgoRR::buildSegments ( const CSCSegment *  cscsegment, const std::vector< const TrackingRecHit * > &  rechits  )

private

Build the GEMCSCSegment.

This algorithm uses a Minimum Spanning Tree (ST) approach to build endcap muon track segments from the rechits in the 6 layers of a CSC and the 2 layers inside a GE1/1 GEM. Fit is implemented in GEMCSCSegFit.cc

Utility functions.

Search for GEMHits inside a Box around the position extrapolated from the CSC segment.

Chain hits :: make a TrackingRecHit vector containing both CSC and GEM rechits take the hits from the CSCSegment and add a clone of them take the hits from the GEM RecHit vector and check whether they are compatible with the CSC segment extrapolation to the GEM plane. If they are compatible, add these GEM rechits
