High-Level Science Products (HLSPs) are collections of high scientific interest that are prepared by members of the MAST community. These are among the most used and most often cited data collections in MAST. Some HLSP collections are available in the Portal, others include catalogs that are accessible via MAST catalog interfaces (see Catalog Data Collections), while others are accessible only through the home page for a given HLSP.

  • See the HLSP page to search for collections of interest.
  • See the HLSP Guide to learn how to contribute HLSPs to MAST.
