Shadowed bright deposit NP05 in the Zatik crater. (a) Color composite with (R, G, B) = (F5, F2, F8). (b) F2 image (low compression ratio) with the contrast enhanced in shadowed areas, revealing the bright deposit. (c) F6 image (high compression ratio) with the contrast enhanced in shadowed areas. (d) F2 image in b with the sampled areas outlined. Outline colors correspond to the curves in e. (e) Spectra associated with the areas indicated in d. Top: bright material spectra, background spectra, and their difference. Bottom: bright material and background spectra divided by the background spectrum. The projections in a–d show the area bounded by latitudes (69.0°, 70.5°) and longitudes (111.0°, 116.0°)E.
