Detailed Description

Description: The FastPrimaryVertex is an algorithm used to find the primary vertex of an event . It takes the pixel clusters compabible with a jet and project it to the beamSpot with the eta-angle of the jet. The peak on the z-projected clusters distribution is our FastPrimaryVertex.

Implementation: [Notes on implementation]
