    12 If you just want to hard-code a cut, all you need to do is modify the file SubProcesses/cuts.f, where all external particle 4-momenta are given in the P(0:3,nexternal) array (energy in P(0,I) and 3-momenta in P(1:3,I)). The order of the external particles depends on the subprocess, and can be guessed from the name of the subprocess Pxxxxxxx directory or can be seen from the Pxxxxxxx/leshouche.inc file.
