Fig. 5: Dune defect density vs crest spacing across planetary bodies.
From: Aeolian sediment transport on Io from lava–frost interactions
The measurements from this work for Io are compared with the power law trend fit to observations on other planetary bodies29. The number of ridges measured at each site on Io are denoted by n. The calculation method for the error bars are described in the “Ridge crest digitization” and “Best-fit trendline for defect density to crest spacing ratio” sections of Methods. Our maximum likelihood fit to the data from other bodies (see Methods) is shown as the thick, dark blue line, with the intrinsic 1σ scatter of that trend indicated by the dashed lines. The best fit parameters are shown. The thin, transparent lines are a sample of less likely fits. Posterior probability distributions for the fit parameters are shown in Supplementary Fig. 5.
