Detailed Description

Identifies the primary vertices.

Primary vertices are identified using up to three different methods. The first method succeeding interrupts the search and the resulting GenVertex is imported to the MCVertices table as a primary vertex.

Methods:

If a vertex was marked as primary when importing the data, no further search is performed for that GenEvent (or collision);
If particles with "signal" status code are found, the production vertex of the particle with lower HepMC ID is assigned the role of PV;
The production vertex of the particle with the lowest HepMC ID is called the PV.

The value of the HepMC status identifying signal particles depends may depend on the generator and is defined as argument of the constructor.
