class AliAODRecoDecay: public AliVTrack

 Default Constructor

 Constructor with AliAODVertex for decay vertex

 Constructor with AliAODVertex for decay vertex and without prongs momenta

 Copy constructor

 assignment operator

 Default Destructor

 Armenteros-Podolanski alpha for 2-prong decays

 Decay length assuming it is produced at "point" [cm]

 Decay length in XY assuming it is produced at "point" [cm]

 Cosine of pointing angle in space assuming it is produced at "point"

 Cosine of pointing angle in transverse plane assuming it is produced
 at "point"

 Only for 2-prong decays:
 Cosine of decay angle (theta*) in the rest frame of the mother particle
 for prong ip (0 or 1) with mass hypotheses pdgvtx for mother particle,
 pdgprong0 for prong 0 and pdgprong1 for prong1

 Decay time * c assuming it is produced at "point" [cm]

 Energy

 Energy of ip-th prong

 This function returns the global covariance matrix of the track params

 Cov(x,x) ... :   cv[0]
 Cov(y,x) ... :   cv[1]  cv[2]
 Cov(z,x) ... :   cv[3]  cv[4]  cv[5]
 Cov(px,x)... :   cv[6]  cv[7]  cv[8]  cv[9]
 Cov(py,x)... :   cv[10] cv[11] cv[12] cv[13] cv[14]
 Cov(pz,x)... :   cv[15] cv[16] cv[17] cv[18] cv[19] cv[20]

 For XYZ we take the cov of the vertex, for PxPyPz we take the
 sum of the covs of PxPyPz from the daughters, for the moment
 we set the cov between position and momentum as the sum of
 the same cov from the daughters.

 We take the logical AND of the daughters cluster maps
 (only if all daughters have the bit for given layer, we set the bit)

 Same as for ITSClusterMap

 compute impact parameters to the vertex vtx and their covariance matrix
 b is the Bz, needed to propagate correctly the track to vertex
 return kFALSE is something went wrong

 Impact parameter in the bending plane of the particle
 w.r.t. to "point"

 Invariant mass for prongs mass hypotheses in pdg array

 Apply mass cut

 2-prong(ip1,ip2) invariant mass for prongs mass hypotheses in pdg1,2

 Check if this candidate is matched to a MC signal
 If no, return -1
 If yes, return label (>=0) of the AliAODMCParticle

 if ndgCk>0, checks also daughters PDGs

 Check if this candidate is matched to a MC signal
 If no, return -1
 If yes, return label (>=0) of the AliAODMCParticle

 Match to MC signal:
 check if this candidate is matched to a MC signal
 If no, return -1
