Function documentation

AliTPCExBExact()

fkMap(0),

 purely for I/O

AliTPCExBExact(const AliMagF* bField, Double_t driftVelocity, Int_t n = 100, Int_t nx = 30, Int_t ny = 30, Int_t nz = 100)

fkMap(0),

 The constructor. One has to supply a magnetic field and an (initial)
 drift velocity. Since some kind of lookuptable is created the
 number of its meshpoints can be supplied.
 n sets the number of integration steps to be used when integrating
 over the full drift length.

~AliTPCExBExact()

 destruct the poor object.

void Correct(const Double_t* position, Double_t* corrected)

 correct for the distortion

void TestThisBeautifulObject(const AliMagF* bField, const char* fileName)

 Have a look at the common part "TestThisBeautifulObjectGeneric".

fkMap=0;

void TestThisBeautifulObjectGeneric(const char* fileName)

 Well, as the name sais... it tests the object.

void CreateLookupTable()

 Helper function to fill the lookup table.

void GetE(Double_t* e, const Double_t* x) const

 Helper function returning the E field in SI units (V/m).

void GetB(Double_t* b, const Double_t* x) const

 Helper function returning the B field in SI units (T).

void Motion(const Double_t* x, Double_t t, Double_t* dxdt) const

 The differential equation of motion of the electrons.

void CalculateDistortion(const Double_t* x, Double_t* dist) const

 Helper function that calculates one distortion by integration
 (only used to fill the lookup table).

void DGLStep(Double_t* x, Double_t t, Double_t h) const

 An elementary integration step.
 (simple Euler Method)

AliTPCExBExact()

AliTPCExBExact(const AliMagF *bFieldMap,Double_t driftVelocity,Int_t n=100);
