Statistical Validation of Transiting Planet Candidates

Project description

A tool for vetting and validating TESS Objects of Interest.

See Giacalone et al. (2021) for more information about this tool.


You can install the most recently released version of this tool via PyPI:

$ pip install triceratops


triceratops can be easily used with jupyter notebook (with Python 3.6 or higher). See the notebook in the examples/ directory for a brief tutorial.


If you use triceratops, please cite both the paper and the code.

If you are having trouble getting triceratops working on your machine, I recommend installing it in a fresh conda environment. You can download the latest distribution of anaconda here. After doing so, run the following in terminal:

$ conda create -n myenv python=3.8
$ conda activate myenv
(myenv) $ pip install triceratops jupyterlab

You can replace myenv with an environment name of your choice. To exit this environment, run:

(myenv) $ conda deactivate

To delete this environment, run:

$ conda remove --name myenv --all
