void ana::MECDoubleGaussEnhSystUP::Shift ( double  sigma,

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
sigmaNumber of sigma to shift record by
srThe record to inspect and alter
weightScale this weight for reweighting systematics

Reimplemented from ana::ISyst.

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).
