Extended Planet Data Contents

Data Columns in the Extended Planet Data Search

The following table lists all of the data columns that can be returned through the Exoplanet Archive's Extended Planet Data Search (referred to as exomultpars in the API), which provides additional, non-default parameters and their literature references for confirmed planets in the Exoplanet Archive. More information about the default parameters in the archive are explained in the FAQ: What are default parameters?
