Note that the weighted events from PEGASUS are normalized by CASCADE, so one should multiply the weights by the total cross section during processing. The total cross section can be found in the CASCADE output or in the ''*.lhe'' file. The produced [[https://www.sciencedirect.com/science/article/pii/S0010465500001892?via%3Dihub | HepMC]] file can be then processed to form necessary cross sections.
