It shows planets (filled circles) and spacecraft (filled squares) projected in the solar equatorial plane, in colors as indicated at the bottom. Large red (blue) circles are CMEs moving at constant propagation speed, with constant direction and constant angular width of 60°, modeled after observations by STEREO-Ahead (STEREO-Behind).
At an impact time, a circle with the color of the spacecraft and size related to the impact speed at the target according to the legend on the lower part of the figure is produced. This „impact circle" fades away with time so an impact is better visible.
