template<>

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

virtual

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.
