This file contains the fiducial cuts on momentum and angular coverage as well as expected energy resolution terms for the electromagnetic and hadronic calorimeters. Electromagnetic and hadronic calorimeter resolution terms will be scaled to achieve the jet energy resolution specified by parameter JETResolution if the boolean parameter JETParameterization is set to true. To perform this scaling properly you must also specify the fraction of the jet energy that is electromagnetic (JETEMEnergyFraction) and the fraction due to neutral hadrons (JETHadEnergyFraction). You can choose to only scale the hadronic energy resolution (JETHadDegradeFraction=1), to only scale the electromagnetic resolution (JETHadDegradeFraction=0), or to scale both using an intermediate value for JETHadDegradeFraction. More information on the jet energy resolution algorithm can be found on pp. 162-163 of the SiD Detector Outline Document.

This provides a simple method for simulating the confusion terms in identifying individual particles. In addition, the parameter wt_charged_track_calorimeter_energy determines how often a charged hadron's reconstructed energy will be set equal to the the calorimeter energy. For example, if wt_charged_track_calorimeter_energy=0 then the tracker momentum will always be used for the charged hadron's reconstructed energy; if wt_charged_track_calorimeter_energy=1 then the calorimeter energy will always be used for the charged hadron's reconstructed energy.
