Dispersed pebbles on Mars: An unexpected setting for hyperuniformity

# Clasts-Pattern-Mars This file contains the data and the codes used in: `Z. Zhu, B. Hallet, A. A. Sipos, G. Domokos, Q.-X. Liu, "Dispersed pebbles on Mars: An unexpected setting for hyperuniformity." arXiv [Preprint] (2023). https://doi.org/10.48550/arXiv.2312.13818` It is sorted by the figures in the article, so there may be duplicates in different folders. The data and code list reads as follows: codes, FIG_xx_yy, MSL image raw data, and Gobi image raw data, where xx and yy represent the figure number and data source, respectively. `density_fluctuation.m` :Two-dimensional density_fluctuation of a set of points. `struct_factor_sq.m` :Two-dimensional static structure factor of a set of points. `clastsrun.m` : individual-based model of the clasts movements on aeolian sands written in MATLAB 2019a. `spectral2D.m` :Two-dimensional spectral analysis of an image file, from http://www.nioo.knaw.nl/homepages/koppel `main.m` :Computation of obeserved data and possion point process in Fig.2. `rippleformation.m` :sand dune model of Werner 1995. `sinuosity.m` :Mean sinuosity of the sand ripples from a binary image. `plot*.m` :Plot of the figure in each folder. `powerspectrum2d.m` :Two-dimensional powerspectrum of an image file. `DJI_*.JPG` :Photos taken by DJI drones at the Gobi desert. # Dataset `MSL image Raw data` :Mars images in Gale Crater downloaded from https://mars.nasa.gov/msl/home/. `*.csv` and `*.mat`:files that save the results of the analyses in each folder for further ploting used in main figures and SI figures. `Gobi image Raw data` :Images of Gobi clasts were collected from Alxa Left Banner.
