Detailed Description

define MonitorEnsembple to be used

Module to apply a monitored selection of top like events in the di-leptonic channel.

Plugin to apply a monitored selection of top like events with some minimal flexibility in the number and definition of the selection steps. To achieve this flexibility it employes the SelectionStep class. The MonitorEnsemble class is used to provide a well defined set of histograms to be monitored after each selection step. The SelectionStep class provides a flexible and intuitive selection via the StringCutParser. SelectionStep and MonitorEnsemble classes are interleaved. The monitoring starts after a preselection step (which is not monitored in the context of this module) with an instance of the MonitorEnsemble class. The following objects are supported for selection:

• jets : of type reco::Jet
• elecs : of type reco::GsfElectron
• muons : of type reco::Muon
• met : of type reco::MET

These types have to be present as prefix of the selection step paramter label separated from the rest of the label by a ':' (e.g. in the form "jets:step0"). The class expects selection labels of this type. They will be disentangled by the private helper functions objectType and seletionStep as declared below.
