These notebooks are a guide to working with TESS data and associated file formats. Much of the content is based on the beginner Kepler notebooks.



Retrieve Data Validation Products

Use astroquery to retrieve Data Validation Products.

Read and Plot a Data Validation Timeseries

Data Validation (DV) timeseries help evaluate the quality of a planet detection.

Read and Display a Full Frame Image

A Full Frame Image (FFI) is created when TESS reads out the entire frame of all four of its cameras. Learn to plot an FFI.

Read and Plot a Light Curve File

MAST stores light curves that were created using TESS data. Learn how to read and plot them.

Read and Display a Target Pixel File

A Target Pixel File records the raw and calibrated flux for a target observed by TESS.

Light Curves through Python Requests

Rather than using astroquery, you can create a Python request to find TESS targets.

Light Curves through TAP

TAP is the Virtual Observatory Table Access Protocol; you can use this instead of astroquery or a Python request to get TESS data.

Searching the TESS Input Catalog

The TESS Input Catalog is a collection of every bright, optically persistent object in the sky. Learn how to search it for a target of interest.

TESS 2-minute Cadence Data

Although TESS FFIs are created on a 30-minute cadence, other, more frequently sampled data products are available.

Generating a Cutout

FFIs are large files; it is quicker to generate a cutout of your target pixels and turn them into a light curve.
