A plugin that implements a reweighting to account for b-tagging scale factors.
Reweighting is performed according to a recipe described in [1]. Tag configuration is not affected, i.e. if a jet is b-tagged, it stays b-tagged after the reweighting is applied. The user can provide a pt threshold, which a jet much satisfy in order to be considered in the procedure. [1] https://twiki.cern.ch/twiki/bin/viewauth/CMS/BTagSFMethods?rev=27#1a_Event_reweighting_using_scale
In the default configuration only the nominal event weight is calculated. Evaluation of the effect of systematic uncertainties can be requested with the help of method RequestSystematics.
This plugin exploits a JetReader (default name is "JetMET") and a number of services to access b-tagging working points ("BTagWP"), efficiencies ("BTagEff"), and scale factors ("BTagSF").
