The Linker
Each Linker reports the best track that passes through a 1.25o phi-slice located at the 3rd axial layer.
Since tracks can curve in the magnetic field, this means that pixels outside of the 1. 25o phi-slice are needed
The total number of roads needed to find all tracks with PT > 1.5 GeV/c in a linker is 2400.
The number of roads grows as 1/Pt(min)
