Figure 1. The I000 Angular function shown with the axes used to define the function. For the parameterisation of the (e,2e) Differential cross section, the z-axis is chosen as the incident electron beam direction. The x-axis is chosen to lie in the Detection plane of the analysers. The colour scheme reflects the sign of the function. PURPLE indicates the function is exclusively POSITIVE.
