TESS Time Correction

This repository shows how the TESS Quick-Look Pipeline applies barycentric time correction to time stamps recorded on the TESS spacecraft using spacecraft position and sky coordinates. It includes both the data files containing the spacecraft position data (2018-2025) and a reference implementation with example usage in the TESS Time Correction notebook.

To run the notebook, make sure you have Python installed on your system and create and activate a virtual environment (or skip this step if you prefer to use the global installation):

python3 -m venv .venv
source .venv/bin/activate

Then install the dependencies and start JupyterLab:

pip install -r requirements.txt
jupyter lab

Finally, in the browser window that opens, select the folder icon in the sidebar to open a file browser and select "TESS Time Correction.ipynb" to view and run the example notebook.
