Les Houches Recommendation regarding detector modeling:
2a) Provide histograms or functional forms of efficiency maps wherever possible in the auxiliary information, along with precise definitions of the efficiencies, and preferably provide them in standard electronic forms that can easily be interfaced with simulation or analysis software.
2b) The community should take responsibility for providing, validating and maintaing a simplified simulation code for public use, reproducing the basic response of the LHC detectors. The validation and tuning of this tool should be based on comparisons with actual performance plots, and/or other
inputs, made available by the experiments along the lines of Recommendation 2a. Limits of validity should be investigated and clearly documented.
