Ganymede 3.6-µm and 4.4-µm reflectance maps. From top to bottom: reflectance images at 3.6 (NRS1) and 4.4 µm (NRS2) for Leading (left) and Trailing (right) hemispheres. Iso-latitude and longitude lines are drawn by increments of 30°. The color scale is different for each map. The reflectance at the spaxels near the limb is somewhat inaccurate, as no PSF correction was applied.
