Member Function Documentation

addExperimentalTOFBKGData()

void NeutronAngularDistAna::addExperimentalTOFBKGData

(

std::string

a_fileName

)

stores 2D time-since-last-RF vs outgoing neutron energy hists in m_tofHistsBKG

addExperimentalTOFData()

void NeutronAngularDistAna::addExperimentalTOFData

(

std::string

a_fileName

)

read in histograms generated by GenesisPhysEventAna::getNeutronEnergyVsTimeSinceRF stores 2D time-since-last-RF vs outgoing neutron energy hists in m_tofHists can also load scint/scint hists from GenesisPhysEventAna::getScintScint... stores in m_tofHistsOrgOrg

drawEffCorrAngDist()

TH2F * NeutronAngularDistAna::drawEffCorrAngDist	(	std::string	a_expFile,
		std::string	a_bkgFile
	)

looking for histogram called "neutronAngularDist_En" which can be made in GenesisPhysEventAna::getNeutronAngularDist()

drawRFExpBkg()

void NeutronAngularDistAna::drawRFExpBkg	(	int	a_detID,
		bool	a_drawSub = false
	)

draw x-projection of m_tofHists histograms for data and background

getAngDistTOF()

void NeutronAngularDistAna::getAngDistTOF	(	int	a_tof,
		bool	a_normalize = false,
		int	a_tofWidth = 8
	)

plots energy-integrated neutron yield at a given TOF for all angles (detectors); a_normalize = true set lowest angle to be at y = 1

Here is the call graph for this function:

getEffData()

EffData NeutronAngularDistAna::getEffData

(

int

a_detID

)

returns efficiency data

getEnerDistTOF() [1/2]

vector< double > NeutronAngularDistAna::getEnerDistTOF	(	double	a_angle,
		double	a_angleWidth,
		double	a_tof,
		bool	a_draw = false,
		bool	a_useEff = true,
		double	a_tofWidth = 8
	)

same as above but for a range of angle i.e. a_angle = 10, a_angleWidth = 5 for 10 +/- 5

getEnerDistTOF() [2/2]

vector< double > NeutronAngularDistAna::getEnerDistTOF	(	int	a_detID,
		double	a_tof,
		bool	a_draw = false,
		bool	a_useEff = true,
		double	a_tofWidth = 8
	)

energy distribution at a given tof fits maxwellian after correcting for efficiency

Here is the caller graph for this function:

getScintScintHist()

TH2F * NeutronAngularDistAna::getScintScintHist	(	int	a_detID,
		bool	a_normEff = false
	)

returns background sub'd set a_normEff=true to normalize by efficiency time-since-last-rf vs outgoing neutron energy from scint/scint

going for 8 ns time bins, .2 MeV energy bins

plot2DEnerDistTOF()

void NeutronAngularDistAna::plot2DEnerDistTOF

(

int

a_detID

)

uses fits to draw time-since-last-rf vs neutron energy

Here is the call graph for this function:

plotEnerDistTOF() [1/3]

void NeutronAngularDistAna::plotEnerDistTOF	(	double	a_angle,
		double	a_angleWidth
	)

Here is the call graph for this function:

plotEnerDistTOF() [2/3]

void NeutronAngularDistAna::plotEnerDistTOF

(

int

a_detID

)

plots integral and temperature from maxwellian fit across TOF domain

Here is the call graph for this function:

plotEnerDistTOF() [3/3]

map< double, std::pair< double, double > > NeutronAngularDistAna::plotEnerDistTOF	(	int	a_detID,
		Eigen::VectorXf	a_calcYield,
		double	a_normalization = -1
	)

same but takes a yield calc'd from sTOF/TALYS and a normalization a_normalization = -1 -> normalize to area

Here is the call graph for this function:

readEfficiencyData()

void NeutronAngularDistAna::readEfficiencyData

(

std::string

a_effFile

)

reads in efficiency data, expecting a tab-delimited file with columns: det ID | det angle | energy bin lower edge | eff | eff error

setBackgroundScaler()

void NeutronAngularDistAna::setBackgroundScaler	(	double	a_bkgScaler,
		bool	a_scintScint = false
	)

set m_bkgScaler for normalization in background subtraction (i.e. target count time / background count time); set a_scintScint=true if scaler is for scint/scint hists default value of m_bkgScaler is 1 default m_bkgScalerOrgOrg = 1

uniBinEfficiency()

void NeutronAngularDistAna::uniBinEfficiency	(	int	a_detID,
		int	a_nBins,
		double	a_lowE = 1
	)

draw efficiency with uniform a_lowE-10 MeV binning
