Overview: The Exoplanet Follow-up Observing Program (ExoFOP) website includes project and community follow-up observation data for Kepler, K2 and TESS. The site is designed to optimize resources and facilitate collaboration in follow-up studies of exoplanet candidates. Users can upload and share information about observations they have taken, data files associated with the observations, and derived physical properties of the host stars and planet candidates. Data are searchable and available for download.
