• if ptMinMeasurements is specified for the given seed collection, applies ptMin cut in branch stopper once ptMinMinMeasurements have been encountered.
• if absEtaMaxMeasurements is specified for the given seed collection, applies absEtaMax cut in branch stopper once absEtaMaxMeasurements have been encountered.
