To add the ReconCheater to a process, use

    add(new org.lcsim.recon.cheater.ReconCheater());

The TrackingCheater and ClusterCheater drivers will be added by the ReconCheater. An AIDA histogram package is included for optional use.

To access reconstructed particles, use

    event.get(ReconstructedParticle.class);

• Only those tracks and clusters that were reconstructed, e.g. by the corresponding cheaters, are used, so particles do get lost.
• For charged particle decays, the track from the primary particle is used if it was found, otherwise the secondary track is used, allowing neutrinos to carry away energy.
• For converted photons, the found tracks are used.
• At this stage, perfect energy flow is used where a cluster's parentage is checked to see if there is a charged track which should be associated.
• Nuclear interactions are turned off by default since the reconstruction is not optimized for them yet: for example should low energy protons be ignored, can low energy neutrons be cut out, can the leading particle be used to get an estimate of the corresponding neutral energy in the calorimeter.
  The original particle (or reconstructed primary track if it's charged) is used and all secondary tracks and clusters are removed. Nuclear interactions can be turned on for comparisons.

The total Z pole energy reconstructed for the CDC, GLD and SiD detectors is shown below. Only uds decays of the Z where simulated for the GLD detector. Here a parameterized HCal response of 60%/sqrt(E) was used to obtain resolutions of 2.1 GeV for all 3 detectors.
