Summary
The Planet Hunters Analysis Database (PHAD) was a search interface that allowed for queries of planet candidates discovered by citizen scientists from TESS data. Planet Hunters is part of the Zooniverse citizen science platform. PHAD was a MAST-created interface that:
- periodically received updates from the Planet Hunters project on classifications of planet candidates by transit and by users, primarily the center and width of possible transit events
- provided a web interface to display a sortable table of transit IDs, TIC star IDs, Center of Transit, Width of Transit, and information on the number of transit counts
- provided a web interface to display a sortable table of every individual transit identification sorted by user name, including the user's estimates for transit center and width
- included an API that allowed for programmatic access via HTTP GET and POST
Retirement
PHAD stopped receiving new classification information from the Planet Hunters team on 22 February 2023. The web search interface was decommissioned with a redirection set in place to this page in April 2024.
