Detailed Description

Fast jet tagger for geometric matching of jets.

Author: Martha Verweij; Markus Fasel marku.nosp@m.s.fa.nosp@m.sel@c.nosp@m.ern..nosp@m.ch, Oak Ridge National Laboratory

Since: Nov 8, 2017

Class based on AliAnalysisTaskEmcalJetTagger. Navigation finding closest neighbor however is based on a kd-tree.

static

Factory creating new jet matching task.

The new task is added to the analysis manager, and the containers for input and output are configured. Requires an analysis manager to be present.

Parameters

[in]	njetsBase	Name of the jet container with base jets
[in]	njetsTag
[in]	R	resolution parameter
[in]	nrhoBase	Name of the $\rho$-parameter object for base jets
[in]	nrhoTag	Name of the $\rho$-parameter object for tag jets
[in]	ntracks	Name of the track container
[in]	nclusters	Name of the cluster container
[in]	type	Name of the acceptance type (TPC/EMCAL) for base jets
[in]	CentEst	Name of the centrality estimator
[in]	pSel	Event selection bitmap
[in]	trigClass	Name of the trigger class (for output container)

Returns: New jet tagger task with basic configuration
