Description: Fits a primary vertex in 1D (z) using the "divisive method"
Implementation: This class was ported from ORCA by me (Aaron). It was originally written by ... Find the PV candidates with a simple divisive method. Divide the luminosity region in several regions according to the track distance and for each of them make a PVCluster. Iteratively discard tracks and recover them in a new PVCluster. Return a sorted vector<Vertex> (aka VertexCollection) with the z coordinate of PV candidates
ntkmin | Minimum number of tracks required to form a cluster. |
useError | physical distances or weighted distances. |
zsep | Maximum distance between two adjacent tracks that belong to the same initial cluster. |
wei | Compute the cluster "center" with an unweighted or a weighted average of the tracks. Weighted means weighted with the error of the data point. |
