Bralgah Crater Boulder Survey and Simulation Data

The ZIP files contain simulation data from using PKDGRAV to simulate mass movements on Bennu. Each ZIP is for the simulations with the named number of particles, and contains the initial setups, as well as FITS files with the final locations and displacements of the boulders. The FITS files also contain headers which contain information about the data, as well as simulation parameters. The NPY file is a Python array of the survey data for boulders at a flow site at the Bralgah crater on asteroid Bennu.The columns for the survey data are as follows:0: Boulder ID1-3: x, y, z coordinates4-5: Lat, lon coordinates6: Major axis length7: Major-minor axis ratio8: Orientation of major axis
