Community tools
This list includes tools and software developed specifically for TESS data, as well as tools developed for Kepler and K2 that can be used or modified for TESS. The data formats are similar for Kepler/K2 and TESS: target pixel files (TPF) and full frame images (FFIs). Kepler and K2 had three data modes: long cadence (30 min) and short cadence (1 min) postage stamps (TPFs), and
quarterly FFIs (30 min). TESS has two data modes, short cadence (2 min and 20 second) postage stamps, and 30 min, 10 min, or 200 sec cadence FFIs. Note that 30 min cadenced data is only available for TESS Cycles 1 and 2, the 10 min cadence data in Cycles 3 and 4, and the 200 sec data in Cycle 5+.
Many tools are under development, and some are more robust than others. The TESS GI Office plans to update this list as new tools, software, and tutorials become available. If you have any tools you would like us to include, please contact us at tesshelp@bigbang.gsfc.nasa.gov.

| Juliet |
A versatile modelling tool for transiting and non-transiting exoplanetary systems that allows users to perform quick-and-easy fits to data coming from transit photometry, radial velocity or both using bayesian inference and, in particular, using Nested Sampling in order to allow both efficient fitting and proper model comparison. Tutorials can
be found here.

| TESSreduce |
This builds on lightkurve, allowing the user to reduce TESS data while preserving transient signals. The user can supply a TPF or give coordinates and sector to construct a TPF with TESScut. The background subtraction accounts for the smooth background and detector straps. Alongside background subtraction TESSreduce also aligns images, performs difference imaging, and can even detect transient events!
