abhinav-s-jindal/67P_sediment_transport_pathways: Initial Release - Comet 67P Sediment Transport Analysis

Comet 67P Sediment Transport Pathways - Initial Release

This release contains Python code and data for analyzing sediment redistribution on comet 67P/Churyumov-Gerasimenko through ballistic transport simulations.

Contents

Python Scripts:

• create_hop_stats.py - Multi-hop sediment redistribution simulation
• convert_hop_stats_to_vtk.py - Convert particle distributions to VTK format
• generate_spatial_index.py - Generate spatial index for interactive visualization
• trajectory_source_visualizer.py - Interactive reverse trajectory analysis tool

Data Files:

• Shape model (OBJ format, 440,596 facets)
• Ejection probability maps (TXT and VTK formats)
• Documentation and README files

Large Data Files

⚠️ Note: The pre-computed transport dictionaries (~5 GB) are too large for GitHub and are available separately on Zenodo:

• DOI: https://doi.org/10.5281/zenodo.17574912

Requirements

• Python 3.7+
• NumPy, SciPy, VTK

Documentation

See README.md for complete installation instructions, usage examples, and methodology.
