This repository contains the default files that are downloaded when installing the TU Delft Astrodynamics Toolbox (Tudat) software.
- For more details on the project, we refer to the project website and our project Github page.
- Conda package for this repository are available on anaconda, which is built through the tudat-feedstock on Azure
Part of the contents of this repository are taken from external sources, which are listed below:

NOTE, when installing the tudat-resources conda package (https://anaconda.org/tudat-team/tudat-resources, a required dependency of tudat), a number of additional files that are not under version control (since their size is >100 MB) are downloaded. The complete set of files that is downloaded is contained in the resources.tar.gz of the corresponding pacakge version here: https://github.com/tudat-team/tudat-resources/releases
