All momenta are given in the Lab. frame. Used mass of Lambda is 1.115684 GeV.
The neutron (line 6) and pion (line 7) are from the
L decay.
The Monte Carlo (MC) events are reconstructed
after the detector simulation program.
In the MC file there are 4 additional lines which provide the information
about the generated 4-momenta: beam K-, Lambda, pi0_1, pi0_2.
The information for the generated decay products
of Lambda is not given, as the decay was made by GEANT.
The total cross section
numbers correspond to the Monte Carlo integral over the reconstructed MC events.
