Detailed Description

This processor will choose primary verities (PV) satisfying selection criteria and write selected objects to the new branch in new Tree.

Usage: add this processor to the controller Run processor, e.g.
cafe.Run ... VertexSelector(processor_name) ... You can change default behavior via configuration file.

Usage:

Required parameters: -.From: Name of the input vertex branch

Optional parameters:

• .Tree: OutputTreeName[default: name()]
• .To: Name of the output branch name [default: .From branch name]
• .Sort: sort selected vertices according to the minimal bias probability [default: false]

Cuts (optional):

• .nPVMax: maximal number of vertices to be selected [default: -1 (no selection)]
• .zmax: maximal absolute value for PV z in cm [default: 60 cm]
• .ntracks: minimal number of tracks associated with PV [default: 3]

The following selectin is not working correctly at the moment with branches created by Muon and Electron Selctors (problem with TRef)

• .dz_muon: maximal absolute distance in Z between muon and PV. If dz <=0 no cut is applied. [default: 0]
• .muonBranch: muon branch name to be used for the previous selection. At least one muon from the branch must satisfies the selection [default: ""]

• .dz_electron: maximal absolute distance in Z between electron and PV. If dz <=0 no cut is applied. [default: 0]
• .electronBranch: electron branch name to be used for the previous selection. At least one electron from the branch must satisfies the selection [default: ""]
• .UseEOPTrackMatchElectron: must be set to 1 (true) if the EOP track matching is used in caf_util::ElectronSelector [default: false]

Member Function Documentation

void caf_util::VertexSelector::before (  cafe::Collection< TMBPrimaryVertex > &  from  )  [private, virtual]

Called before the actual selection starts. E.g. the input can be sorted here. Reimplemented from cafe::SelectUserObjects< TMBPrimaryVertex >. Definition at line 204 of file VertexSelector.cpp. References _sort, cafe::Collection< T >::begin(), cafe::Collection< T >::end(), and cafe::Collection< T >::sort().

void caf_util::VertexSelector::begin (   )  [virtual]

Called at beginning of processing. Reimplemented from cafe::Processor. Definition at line 51 of file VertexSelector.cpp. References _finder, cafe::Processor::debug(), and caf_util::TRefFinder::setDebug().

caf_util::VertexSelector::ClassDef (  VertexSelector  , 0  )  [private]

bool caf_util::VertexSelector::processEvent (  cafe::Event &  event  )  [virtual]

Called for every event. Reimplemented from cafe::SelectUserObjects< TMBPrimaryVertex >. Definition at line 55 of file VertexSelector.cpp. References _event, _nselected, _nvsmax, _stat, cafe::StatPointer::EventSelected(), and cafe::EventBase::get().

bool caf_util::VertexSelector::selectObject (  const TMBPrimaryVertex &  vertex  )  [virtual]

Abstract select method to be overridden by user. Each object for which this method returns true will be put into the result branch, rejected objected will be put in the rejected object branch Implements cafe::SelectUserObjects< TMBPrimaryVertex >.
