Welcome to HLA DR7 (2012 November 2)!
Find out What's New in DR7.
Please take the 2012 MAST User Survey.
Welcome to the Hubble Legacy Archive
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).

WHAT'S NEW in DR7
(November 2012)
NEW DATA PRODUCTS
- HLSP spectra: 586 spectra from the StarCAT project
- Additional HLSP from the Hubble Treasury programs CANDELS, CLASH, PHAT
- New HLSP imaging products: BORG, ORION, GHOSTS
USER INTERFACE ENHANCEMENTS
- Scatter plotting tool that allows users to plot the properties HLA source lists
- The ability to view spectral HLSP through the Interactive Display
- Much faster overlay of catalogs in interactive display
- Spectrum/line plot tool rewritten in HTML5
- Line plots now available for HLSP images
- Footprint view automatically adapts for large or all-sky searches to show filtered sky area
WHAT'S NEW in DR6.1
(August 2012)
NEW DATA PRODUCTS
- WFC3 source lists: includes 5201 daophot and 7019 sextractor source lists from observations that have a release date up to 11-30-2011
WHAT'S NEW in DR6
(January 2012)
NEW DATA PRODUCTS
- WFC3 image data: includes ~62% of data from observations that have a release date up to 11-30-2011
- New High Level Science Products
- Additional ACS (updated to release date 2-16-2011), WFPC2 and NICMOS data
USER INTERFACE ENHANCEMENTS
- Interactive Display enhancements, featuring:
- Contrast setting (darker/lighter) is consistent when the image is zoomed
- Save button that creates a JPEG image showing the same region of the image and contrast as the current view. This can be useful for generating publication-quality images from the HLA display. See the
display help for more information.
- The inventory and images interfaces now include a "Select All" button that can be used to select all the datasets in the current list.
- The HLA Simple Image Access Protocol server is now fully compliant with the Virtual Observatory standards. The HLA SIAP server will be added to the VO registry for easy access to HLA data from scripts and other VO tools.
- Searches using lists of positions now show the number of lines in the list.
WHAT'S NEW in DR5
(March 2011)
NEW DATA PRODUCTS
- Completed processing of WFPC2 data
- New high-level science products
- Combined multi-wavelength source lists
USER INTERFACE ENHANCEMENTS
- New, interactive footprint interface
- Panning and zooming capabilities
- Improved controls for instrument selection
- Clearer display of selected data
- New footprint table with filtering and ordering controls, fully integrated with other views
- Interactive retrieval of source properties from image overlay
- Improved flow control for Shopping Cart retrievals
See the release notes for more details.
HLA ESSENTIALS
-
The HLA interface runs in Firefox,
Safari ,
Chrome
Internet Explorer
(versions 8* and 9),
and similar compatible browsers.
*IE8 limitations - the scatterplot and plotting tools do not work on IE8 as it does not support HTML5.
-
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.

Notes:
-
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).
-
Contains almost all ACS data publicly available through 2/16/2011
-
There are 47,919 extracted ACS grism from 153 archival fields.
-
All WFC3 non-GRISM data that were public as of December 1, 2011 have been processed. The data
are undergoing quality review and approximately 60% have been released to date (January 5, 2012).
Additional data will be released as the processing is refined and the result pass our quality review.
-
Source lists for all WFC3 data have been generated and are undergoing quality review.
They will be released as the quality review proceeds.
-
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.
- 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.
