Detailed Description

Namespace for helper functions manipulating things in AtData (and others). Will take in the parameter class to use. If nullptr then looks for it in the runtime DB N.B. FairRoot implentations mean only the primary thread can find things (the underlying static variable referenced FairRun::Instance() is thread_local).

Function Documentation

GetDriftTB()

double AtTools::GetDriftTB	(	double	d,
		const AtDigiPar *	par = nullptr
	)

Get TB that corresponds to a drift of distance d [mm].

Definition at line 37 of file AtDataManip.cxx.

GetHitFunction()

std::unique_ptr< TF1 > AtTools::GetHitFunction	(	const AtHit &	hit,
		const AtDigiPar *	par = nullptr
	)

Get charge as a function of z (mm).

Definition at line 48 of file AtDataManip.cxx.

GetHitFunctionTB()

std::unique_ptr< TF1 > AtTools::GetHitFunctionTB	(	const AtHit &	hit,
		const AtDigiPar *	par = nullptr
	)

Get charge as a function of TB.

Definition at line 74 of file AtDataManip.cxx.

GetIntersection()

template<class Vector1 , class Vector2 >

ROOT::Math::XYZPoint AtTools::GetIntersection	(	const std::vector< Vector1 > &	point,
		const std::vector< Vector2 > &	direction
	)

Get the intersection (or point of closest approach) between two lines. The lines are parameterized as point[i] + t*direction[i].

Definition at line 32 of file AtVectorUtil.h.

GetRotationToZ()

template<class Vector >

ROOT::Math::AxisAngle AtTools::GetRotationToZ

(

const Vector &

vec

)

Get the rotation matrix that will take vec and make it the z-axis. That is vec*GetRotationToZ(vec) == |vec|\hat{z}.

Definition at line 20 of file AtVectorUtil.h.

GetTB()

double AtTools::GetTB	(	double	z,
		const AtDigiPar *	fPar = nullptr
	)

Get TB that corresponds to the passed z position [mm].

Assumes that window is at z = 0, and the electrons are drifting towards the pad plane at the z locations specified in the parameter file.

Definition at line 21 of file AtDataManip.cxx.

SplitString()

std::vector< std::string > AtTools::SplitString	(	const std::string &	s,
		char	delim
	)

split string, s, into vector of tokens split by delim.

Definition at line 6 of file AtStringManip.cxx.
