AliFemtoEventReaderKinematicsChain()

constructor with 0 parameters , look at default settings

AliFemtoEventReaderKinematicsChain(const AliFemtoEventReaderKinematicsChain& aReader)

 Copy constructor

~AliFemtoEventReaderKinematicsChain()

Destructor
delete fEvent;

AliFemtoEventReaderKinematicsChain& operator=(const AliFemtoEventReaderKinematicsChain& aReader)

 Assignment operator

AliFemtoString Report()

void SetConstrained(const bool constrained)

 Select whether to read constrained or not constrained momentum

bool GetConstrained() const

 Check whether we read constrained or not constrained momentum

AliFemtoEvent* ReturnHbtEvent()

 Get the event, read all the relevant information from the stack
 and fill the AliFemtoEvent class
 Returns a valid AliFemtoEvent

void SetStackSource(AliStack* aStack)

 The chain loads the stack for us
 You must provide the address where it can be found

void SetGenEventHeader(AliGenEventHeader* aGenHeader)

 The chain loads the generator event header for us
 You must provide the address where it can be found

void SetRotateToEventPlane(short dorotate)

void SetUseMultiplicity(AliFemtoEventReaderKinematicsChain::EstEventMult aType)

Float_t GetSigmaToVertex(double* impact, double* covar)

 Calculates the number of sigma to the vertex.

void CopyAODtoFemtoV0(TParticle* tv0, AliFemtoV0* tFemtoV0)
