void ana::MECDoubleGaussEnhSystDOWN::Shift ( double  sigma, caf::SRProxy *  sr, double &  weight  ) const

inlineoverridevirtual

Perform the systematic shift.

Override this function if your systematic depends on non-SRNeutrino quantities. If it is SRNeutrino-only, implement the other function, and let this default forward to you when necessary.

Parameters

sigma	Number of sigma to shift record by
sr	The record to inspect and alter
weight	Scale this weight for reweighting systematics

Reimplemented from ana::ISyst.

virtual void ana::ISyst::TruthShift ( double  sigma, caf::SRNeutrinoProxy *  nu, double &  weight  ) const

inlinevirtualinherited

For systematics that deal only with the neutrino truth and not any reconstruction/PID details. Systematics defined this way will work on nuTree-derived spectra too (e.g. denominators of efficiencies).

Reimplemented in ana::BeamSyst, demo::DemoSyst1, ana::GenericSystComponentScale< T >, ana::GenericSystComponentScale< T >, ana::GenericSystComponentScale< T >, ana::ReinteractionSyst, and ana::NOvARwgtSyst.

      // Implement this function if your systematic depends only
