The Hubble Legacy Archive (HLA) is designed to optimize science from the Hubble Space Telescope by providing online, enhanced Hubble products and advanced browsing capabilities. The HLA is a joint project of the Space Telescope Science Institute (STScI), the Space Telescope European Coordinating Facility (ST-ECF), and the Canadian Astronomy Data Centre (CADC).

HLA ESSENTIALS

• The HLA interface runs in Firefox, Safari (versions 3, 4 and 5), Chrome Internet Explorer (versions 7 and 8), and similar compatible browsers.
• To fully realize all of the HLA's functionality, one must have cookies and popups enabled.
• The HLA includes enhanced data products (ACS, WFPC2, & NICMOS images, ACS & WFPC2 source lists, ACS & NICMOS extracted grism spectra, prototype ACS mosaics) and also provides access to the standard HST data products when HLA enhanced products have not yet been created.
• Footprints, which graphically display the sky coverage on a background image from the Digitized Sky Survey, are available for both standard and enhanced HST data products, including extracted grism spectra and community-contributed high-level science products.
• Here is a matrix describing what is and is not in the HLA:
