Member Function Documentation

AddPeak()

Int_t GamR::Processor::TimeWalk::AddPeak	(	std::string	dataset,
		GamR::Nucleus::Photon	photon,
		Double_t	time )

Add a calibration peak to be used to create a data point in the time walk curve.

Parameters

[in]	dataset	Filename of Data Set, expects output from GamR::Sort::Type::TimeWalkCal
[in]	photon	Calibration peak to measure time relative to reference photon.
[in]	time	Early/Delay time correction of this peak. Positive corrects for delayed transitions, negative for early.

Returns

int Error code: 0 successful, 1 error opening file, 2 can't find reference photon in data set.

Draw()

void GamR::Processor::TimeWalk::Draw	(	TCanvas *	c,
		Bool_t	fits = kFALSE,
		std::string	saveas = "" )

Draws Time Walk graphs.

Parameters

[in]	c	Canvas to draw on.
[in]	fits	Draw fits behind graphs
[in]	saveas	(optional) save to file

MakeGraphs()

void GamR::Processor::TimeWalk::MakeGraphs	(	Int_t	ntoys,
		Bool_t	showmc = kTRUE )

Iterating through calibration peaks for each detector pair: calculate the time difference spectrum (with full background subtraction), monte-carlo the first order moment, correct for any early/delay shifts due to lifetimes, to create one data point on the graph.

Parameters

ntoys	Number of toy experiments to conduct during the Monte-Carlo simulation.
showmc	Shows visualisation of Monte Carlo simulation
