Fig. 2: Global streak and RSL geostatistics.
A Pie charts of terrane age distribution of bright streaks, dark streaks, and RSL; co-located bar chart indicates their distribution over the northern (black) and southern (gray) hemispheres82. B Histograms for slope streak (bright, tan; dark, solid black), RSL (red), and background (black line) distributions over a range of thermophysical properties31,81,83). Note the blue line at TES albedo 0.26, as spatially visualized in Fig. 3. Average values indicated. Note that the relatively low spatial resolution of most of the global thermophysical datasets might blur certain relations, most prominently for the MOLA slope angle dataset, which largely underestimates the actual slope angle at the streak-scale. C AFDs of estimated feature area; \(\surd 2\) binning is used, power law fits indicated by lines, power law exponents indicated by numbers. Note that the lack of small slope streaks is caused by the spatial resolution of the used CTX images (6 m); RSL are only resolvable at the HiRISE scale (0.3 m).
