Upper left panel: 5 by 5 map towards Ganymede at a distance of 1.2 × 10⁶ km. The phase angle is 0°. Moment-zero maps are similar to those presented in Fig. 8, and spectra are baseline subtracted. Upper right panel: same as the upper left panel, but for a phase angle of 60°. Lower left panel: same as the upper left panel, but for a phase angle of 90°. Lower right panel: same as the upper left panel, but for a phase angle of 135°.
