CMU and CMP chambers cover |eta| < 0.6. A muon that has hits in both CMU and CMP is called "CMUP"
the CMX chamber covers 0.6<|eta|<1.0
the BMU chamber covers 1.0<|eta|<1.5
The efficiency of linking a reconstructed muon stub to a track is shown below for each of the three muon categories.
The Identification efficiency includes requirements on the maximum energy in the calorimeter, the isolation, tracking quality cuts and matching cuts between the stub and the track. It is displayed separately below.
Also shown is the total efficiency of both ID and reconstruction.
