High-Level Science Products (HLSP) are community contributed, fully processed (reduced, co-added, cosmic-ray cleaned etc.) images and spectra that are ready for scientific analysis. HLSP also include files such as object catalogs, spectral atlases, and README files describing a given set of data.
Search below to find HLSP of interest by product, object type, and/or wavelength. Select more than one item in each list by using the shift and the control keys. Click on the "search" button for a list of the products for that project. The title of the project is a link to more information about the project. You may search for specific targets by using the HLSP search page. You may also be interested in more information about download options. MAST encourages the submission of HLSP based on data from its missions. Please consult the Guidelines for Contributing HLSP for more information.
