Detailed Description

Singletone class to gather local information about the hits.

Because of the reassignment of secondary hits and the different definition of the right left passage in the CDCSimHit compared to the definition used in tracking finding, we provide this class to collect an manage localised information about each hit such as the local direction of travel and said left right passage information.

getClosestPrimaryDriftLength()

double getClosestPrimaryDriftLength

(

const CDCHit *

const

Look up the drift length from the primary ionisation to the wire from related simulated hit.

If no primary sim hit is available use the information from the secondary hit

getClosestPrimaryRecoPos3D()

Vector3D getClosestPrimaryRecoPos3D
