Method Detail

isPrimary

boolean isPrimary()

Checks if the Vertex is the primary vertex of the event. Only one primary vertex per event is allowed

getAlgorithmType

String getAlgorithmType()

Type code for the algorithm that has been used to create the vertex - check/set the collection parameters AlgorithmName and AlgorithmType.

getChi2

float getChi2()

Chi squared of the vertex fit.

getProbability

float getProbability()

Probability of the vertex fit.

getPosition

float[] getPosition()

Position of the vertex

getCovMatrix

float[] getCovMatrix()

Covariance matrix of the position (stored as lower triangle matrix, i.e. cov(xx),cov(y,x),cov(y,y) ).

getParameters

float[] getParameters()

Additional parameters related to this vertex - check/set the collection parameter "VertexParameterNames" for the parameters' meaning.

getAssociatedParticle

ReconstructedParticle getAssociatedParticle()

Returns Reconstructed Particle associated to the Vertex
