Detailed Description

template<typename T>
class BetaStarVarProducer< T >

Description: This produces value maps to store CHS-related variables for JERC. This includes the charged hadrons associated to CHS jets, and those associated to PU that are within the CHS jet.

Implementation: This uses a ValueMap producer functionality, and loops over the input candidates (usually PackedCandidates) that are associated to each jet, counting the candidates associated to the PV and those not.
