Instructions

The Anaconda conda environment is given should this be needed

All Jupyter Notebooks are ready-made to produce the raw data, intermediate and end data products

Gaia raw data is downloaded in the Jupyter Notebook "R136_runaway_candidates.ipynb"

Data from the literature is given in the subdirectory /tables/ or /input_files/

Input images and files are given in the subdirectory /input_files/

Intermediate and end data products are given in /output_files/

Figures in the paper are produced in the Jupyter Notebooks in the subdirectory /figures/ and stored in the subdirectory /figures/figures_paper/

Expected Output

Jupyter Notebooks can be executed by "Run" -> "Run All Cells"

The Jupyter Notebook show the expected output in their respective cell

Expected runtime are given at the top of each Jupyter Notebook

The Jupyter Notebook which takes the longest "R136_runaway_search.ipynb" takes 7-8 hours for the entire dataset

A small dataset has been given in this Jupyter Notebook as a proof-of-concept

Instructions for use

Jupyter Notebooks can be executed by "Run" -> "Run All Cells"

Figures

Figures can be reproduced from the /figures/ folder.

All material and data used are available either in the Raw Data or in the Intermediate Data

The figures shown in the paper will be saved in ./figures/figures_paper/ folder.
