Map the event at the parton level to the event at the level of reconstruction (or analysis). The map is built by using fully simulated events (here we use Delphes as a proxy for the FullSim at the test stage).

Current status: virtual bird

• Extract from a Delphes ttbar file a simple text file containing all the partons up to the point of showering, and all the reconstructed objects in a very simple format. There will be one block per event. (Sezen)
• Build the code that reads the partons, bins them using Turtle (Harrison)
• Build the code that maps the binned partons to the reconstructed objects. Perhaps use deltaR for forming an association between partons and the reco objects. The prototype will not have a jet algorithm so there will be a many-to-one mapping from partons to reco objects.
• Provide code to store the binned partons and the map in a ROOT file, and a code to read that file back into the memory
• Provide a code that returns a list of reco objects, given a list of partons.
• Test (Benjamin)
