This contains all of the scripts and data files necessary to reproduce the figures in the paper "Dust density enhancements and the direct formation of planetary cores in gravitationally unstable discs" by Rice et al. (2025) - Published in Monthly Notices of the Royal Astronomical Society, https://doi.org/10.1093/mnras/staf714. An arXiv preprint version of the article can also be found at https://arxiv.org/abs/2505.00363. A detailed README file is included as part of the submissions and explains the data files that have been included and where to find the python scripts that can reproduce the figures in the paper. We've only provided the data files necessary to reproduce the figures. Initial data files and those or intermediate steps are available on request.
