The Hubble Heritage Project and MAST maintains this repository of high-level science products associated with some of the Heritage press releases. This is the scientific data (in FITS format) used to create the Heritage color composite press release images. The data has been expertly prepared, significantly beyond the standard pipeline processing. This usually involves careful image registration, combination, and cleaning via drizzling, making it a ready for further scientific analysis and educational use. These data are typically made available at the time of the associated press release, and each include a README file with data reduction details. Their inclusion as MAST High-Level Science products (HLSP) also means this data can be found via MAST archive queries.

The data can typically be downloaded from the lists of files for each target through your browser or via anonymous ftp:
