Constructor & Destructor Documentation

ana::PredictionInterp::PredictionInterp	(	std::vector< const ISyst * >	systs,
		osc::IOscCalc *	osc,
		const IPredictionGenerator &	predGen,
		Loaders &	loaders,
		const SystShifts &	shiftMC = kNoShift,
		EMode_t	mode = kCombineSigns
	)

Parameters

systs	What systematics we should be capable of interpolating
osc	The oscillation point to expand around
predGen	Construct an IPrediction from the following information.
loaders	The loaders to be passed on to the underlying prediction
shiftMC	Underlying shift. Use with care. Mostly for PredictionNumuFAHadE. Should not contain any of of systs
mode	In FHC the wrong-sign has bad stats and probably the fits can't be split out reasonably. For RHC it's important not to conflate them.
