Individual contributions to electron energy distribution function (EDF) as measured by virtual SWA-EAS in the simulation run A (top row) and run B (middle row) are shown as a function of the energy for different source surface locations of the secondary emissions (left panels) and photo-emission (right panels): the SWA-EAS (blue), the spacecraft body (green), the solar panels (orange), the heat shield (purple), the boom (brown), the SWA-EAS baffle (red), and the HG antenna (pink). The simulated spacecraft potential is plotted with the vertical dashed black line for reference. In the top row (run A) the dotted line represents the additional potential barrier created in the spacecraft wake. The geometry of the source locations projected to the XZ and YX plane is plotted in the bottom panels.
