Close × 2022 March 19: The HLA footprint viewer no longer works because it relies on Flash. If you need footprints, we recommend using the MAST Portal. Note that the Portal also gives access to the new Hubble Advanced Products (HAP), which include more recent observations. The HLA contains no observations acquired after 2017 October 1.

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).

Notes:
  1. Fraction of all HST data for which the HLA currently includes enhanced products. Note that the HLA searches and footprints also include standard products. Proprietary data and other data not yet processed by the HLA project are available through DADS requests (which may also be submitted using the HLA cart). Observations with guide star acquisition failures, zero exposure times, and similar problems are excluded. Some observing modes (moving targets, spatial scans, grisms, ramp filters, etc.) are processed only as single exposures rather than being combined.
  2. Contains essentially all ACS data publicly available through 2017 October 1. Also includes almost all data from the HRC, which ceased operation in January 2007.
  3. This is the fraction of HLA-processed ACS/WFC and ACS/HRC visits that have at least one SExtractor or DAOphot catalog. The fraction for ACS/WFC alone is higher (98%). These fractions exclude visits that are too heavily contaminated by cosmic rays to be usable for catalogs due to poor observing strategies.
  4. There are 47,919 extracted ACS grism from 153 archival fields. The most recent data included in the ACS grism were taken in February 2006.
  5. This is the fraction of HLA-processed WFPC2 visits that have at least one SExtractor or DAOphot catalog.
  6. Contains almost all WFC3 data publicly available through 2017 October 1.
  7. This is the fraction of HLA-processed WFC3 visits that have at least one SExtractor or DAOphot catalog. These fractions exclude visits that are too heavily contaminated by cosmic rays to be usable for catalogs due to poor observing strategies.
  8. Reprocessed NICMOS data through the latest STScI calibration pipeline. Data requiring SAAClean have undergone additional processing and have now been released. See the NICMOS Data Handbook for details.
  9. Enhanced data products have been produced for some of the Early Release Observation COS data and have been included in the HLA, together with similar WFC3 data. As for other HST instruments, standard raw and calibrated products for non-proprietary COS data are available through both the MAST and the HLA interfaces.
