0018  *  This provides recommendations to CMS for the stub window sizes to be used in the FE electronics.
0019  *  It prints the output as a python configuration file in the form of
0020  *  L1Trigger/TrackTrigger/python/TTStubAlgorithmRegister_cfi.py .
0021  *
0022  *  The recommendations are based on the TMTT method of using the stub bend. Whilst they give 
0023  *  high efficiency, they do not take into account the requirement to limit the FE electronics band-width,
0024  *  so tighter cuts may be needed in reality.
