Abstract

The Hubble Legacy Archive (Data Release 2 Includes WFPC2 Observations)

Lee Quick (STScI)

The Hubble Legacy Archive (HLA) has entered its Data Release 2 (DR2) phase of operation. The goal of the HLA is to optimize the science coming from the Hubble Space Telescope by providing better browsing capabilities and easy access to both standard and enhanced Hubble products. The project is a collaboration between the Space Telescope Science Institute (STScI), the Space Telescope European Coordinating Facility (ST-ECF), and the Canadian Astronomy Data Centre (CADC).

The highlight of DR2 is the inclusion of enhanced WFPC2 images produced by CADC. This more than triples the number of enhanced HLA images. In addition, the number of ACS source lists has more than tripled, with ~70 % of the ACS images having both DAOphot and SExtractor lists. A number of major user-interface improvements have also been added, including a "shopping cart" to download more than one file at a time, an enhanced plotting tool, overlays of GSC2, 2MASS, SDSS and FIRST catalogs, user-defined search lists, and much faster footprints.

The HLA currently contains enhanced products for ACS, WFPC2, and NICMOS GRISM extractions (from ST-ECF), and provides access to standard products for NICMOS, STIS, FOS, and GHRS via MAST.
