Detailed Description

Discriminate jets originating from the hard-scatter event from pile-up jets, based on the fraction of tracks within the jet that are associated to the hard-scatter vertex. Jets outside the tracking acceptance are considered to originate from the hard-scatter event per default. Optionally, they can be classified as pile-up.
