Function documentation

AliCFPair(AliVParticle* t1, AliVParticle* t2)

 2-track ctor

AliCFPair(AliESDv0* v0, AliESDEvent* esd)

 V0 ctor

AliCFPair(AliAODv0* v0)

 V0 ctor

AliCFPair(const AliCFPair& c)

 Copy constructor.

AliCFPair& operator=(const AliCFPair& c)

 assignment operator.

Bool_t PxPyPz(Double_t* p) const

 sets pair total momentum in vector p

Double32_t P() const

 returns pair total momentum norm

Double32_t Px() const

 returns pair X-projected momentum

Double32_t Py() const

 returns pair Y-projected momentum

Double32_t Pz() const

 returns pair Z-projected momentum

Double32_t Pt() const

 returns pair transverse (XY) momentum

Double32_t E() const

 returns pair total energy according to ESD-calculated mass

Bool_t XvYvZv(Double_t* x) const

 sets pair position to x
 since this class is designed for resonances, the assumed pair position
 should be the same for both tracks. neg track position is kept here

Double32_t Xv() const

 returns pair X-projected position

Double32_t Yv() const

 returns pair Y-projected position

Double32_t Zv() const

 returns pair Z-projected position

Double32_t Phi() const

Double32_t Theta() const

 returns pair theta angle (in YZ plane)

Double32_t Eta() const

 returns pair pseudo-rapidity

Double32_t Y() const

 returns pair rapidity

Double32_t M() const

 returns pair invariant mass
 in case of a V0, returns the current mass hypothesis
 otherwise returns ESD-calculated mass
