Left: surface reflectance map of Ganymede in the spectral interval [140 nm, 150 nm], obtained by fitting the reflected solar continuum. This reflectance map was derived from the Juno/UVS spectral cube convolved at high spatial resolution using a latitude-longitude window of 5^° × 5^°. Right: uncertainty map associated with the reflectance, expressed as a percentage of the fit value at each (latitude, longitude) position, using the same spatial resolution as for the top map.
