Caption: Figure 12.
Obstructions to SPAN-B’s FOV. The inner boundary of the instrument’s full, unobstructed FOV is shown by the beige boundary, within which the instrument does not measure electrons. The spacecraft intrusions to the SPAN-B FOV are substantially greater than SPAN-Ae and are shown in blue, including Sun sensors, solar panels, fuel filling ports, FIELDS antennas, hi-gain antenna, and more. An estimate of the actual blockage, thermal blankets included, is shown in gray.
