Introducing the MAST Catalog Schema Browser

Need to know what’s in a MAST catalog before you write a TAP query or perform a Catalogs Search? The new Catalog Schema Browser lets you explore missions, catalogs, tables, and columns in one place—including data types, units, unified content descriptors (UCDs), and descriptions. Search by name or keyword, or browse from mission down to the table columns. Start with Gaia Data Release 3, PanSTARRS Data Release 2, or the TESS Input Catalog at mast.stsci.edu/schema_browser, with other MAST catalogs coming soon!
