The hit errors initialization in VeloKalmanHelpers
The MR: !2612 (merged)
which introduced not negligible changes for the Primary Vertex reconstruction as shown in update reference (PrimaryVertexChecker): Moore!1752 (merged) and in @adudziak's presention: link
The change has been introduced since Moore v53r7.
Present hit error initialization slightly decreases global efficiency (~ -2 p.p.) and increases global fake rate (~ +2 p.p.).
We would like to reintroduce a change in VeloKalmanHelpers fitForward()
, fitBackward()
, fitBackwardWithMomentum()
methods:
F( VeloKalmanParam::wx ) -> 100.f
F( VeloKalmanParam::wy) -> 100.f
The origin of this difference must be followed up and understood.
