After computing and displaying the electron trajectories the program plots two pieces of data. The first is the cumulative profile of Xray generation in the solid, calibrated in angstroms and the 0% and 90% values are drawn in to enable the value to be measured easily. The second display calculates the Xray signal that would be observed from a thin unit width plane-parallel layer such as a monolayer of some material sandwiched between two grains. ------------------------------------------------------------------------
