        Please use this macro (by Stephen Maple) to find the Kinematics of scattered electron:

        The electron kinematics calculation is implemented in line 24 and takes the Lorentz vectors of the beam electron, scattered electron, and beam proton/ion as inputs. The required four-vectors can be obtained from the corresponding reconstructed particles. By default, ScatteredElectronsTruth_objIdx.index is used to identify the scattered electron, which reproduces the  InclusiveKinematicsElectron method.

        For a more realistic electron-finding approach, replace:
        ScatteredElectronsTruth_objIdx.index with ScatteredElectronsEMinusPz_objIdx.index.

        ScatteredElectronsEMinusPz identifies reconstructed particles with a track–cluster match satisfying 0.9 < E/p < 1.2. It provides good performance in most regions, with reduced performance at high inelasticity and near the barrel–endcap calorimeter transition. The Podio-based electron finding is more advanced.
