Catalogs

Tables of measurements made on sources and objects detected in the processed images, and tables of survey metadata for the observations.

The schema browser includes column descriptions for all tables.

Catalog data products are available via TAP, and most are also available with the Butler. See the Data access and the Tutorials pages to get started with these services.
