' Barrel:

' track segments from a linear fit

' ready and fully tested

' Endcap

' track segments from a helix fit

' ~ready -> need test and debug !!

' Barrel and Endcap LPR output "common" state vector (RecHit)

' common DetUnit and DetLayer description

no additional interpreter is required to exchange information between the 2 sub−system
