This package provides tools to set a weight to reconstructed primary vertices, in order to select the one coming from the hard-scatter interaction.

SumPtVertexWeightCalculator: return sumPT / sumPT2 of the tracks associated to the vertex.
TrueVertexDistanceWeightCalculator: return 1 / deltaZ, where deltaZ is the distance between the reconstructed vertex and the true vertex.
BDTVertexWeightCalculator: BDT-based, developed by Davide Riva during his bachelor thesis.
