Weighted surface albedos (symbols) in the methane windows extracted from VIMS using radiative transfer analysis for crater floors (upper) and the ejecta blankets (lower) of the dune and plain impact craters. The percentages next to the names in the labels correspond to the haze contributions to the data with respect to Huygens’ DISR measurements. The dashed magenta lines are drawn to show the distinction between the spectral responses between the dunes and the plain craters at specific wavelengths. Note that Sinlap and Menrva are not included in this figure, but are treated as special cases later in the manuscript. HLS stands for Huygens Landing Site.
