Mission Stars

Data Columns in the Mission Stars Table

The following table lists all of the data columns in the Mission stars table that can be returned through the Exoplanet Archive's application programming interface (API), or when using the interactive table.

More details on the Mission stars list are given here on the Mission Stellar resources page.

Some data include more specific information that can also be retrieved as separate calls in the API. These include:

  • Uncertainties (positive and negative)
  • Source
