Transiting Planets Table Data Column Definitions
The following table lists all of the data columns in the Transiting Planets Table (TD), which is simpler interface for accessing all of the transit-specific observables currently in the Exoplanet Archive. These data are a subset of what is available in the Planetary Systems and Planetary Systems Composite Data tables. Transit table data may also be retrieved by query through the archive's Table Access Protocol (TAP) service.
Query-based Access to the Transit Table
The Transiting Planets Table is connected to the archive's TAP service, which enables automated data retrieval using queries. To build a query, review the TAP User Guide and use the database column names on this page.
