The ST-ECF ceased operations on December 31, 2010. Plans are being implemented to migrate the European HST Archive to ESA's European Space Astronomy Centre (ESAC), Spain, where most of ESA's Space Science Archives are located and operated from. In the meantime and during the migration period (2011), the European HST Archive will still be operated with ESA support from within the ESO Science Archive Facility. It will continue to serve data in the same way as previously. Support and handling of emergencies will be done on a best-effort basis. For questions and help regarding the archive and its data products please contact hst-archive@eso.org
A classical-style search interface is available here. The HLA grisms are available here or at their dedicated search interface, including the full release of the 47919 ACS Grism spectra.
New
This list gives the main new features
10 October 2010
Added High Level Science Product category as of now containing GOODS products.
Greatly improved download speeds for HST/HLA data products
10 June 2010
Integration of the full set of WFPC2B associations into the system
Smart autocompletion added to the one-line interface and the form-based one.
Added One-line interface (please see Query help and the tooltip on "One-line query" for more information) including drag&drop support for keywords from the form interface part.
Added the option to upload files with target names and/or coordinates
Included the metadata of ST-ECF HLA Grism products into this interface. They also can be accessed through a specific search interface.
Added the retrieval of pedigree information for the datasets to the result page.
Added the possibility to search for solar bodies (BETA version!).
Improved the usability of the interface (allows to send previews to Aladin/Specview/VOspec, hiding and showing individual columns is easier, all rows on a page can be selected/unselected at once)
Additional queries
We provide a few specialised queries for specific instruments or for ancillary databases:
Please send bugs, feature requests or comments to archive@eso.org. Any comments are highly appreciated.
HST Cache
The HST Cache is an automatic system to reprocess and recalibrate all HST datasets on a 24/7 basis using the latest software and reference files. The products are then stored on spinning disks for
immediate download or delivery through VO protocols.
HLA products
All refereed publications based on data obtained from the HLA are requested to carry the following footnote:
Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA).
In addition, publications of research supported by an STScI grant must carry the following acknowledgment:
Support for Program number ____________ was provided by NASA through a grant from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Incorporated, under NASA contract NAS5-26555.
HST products
All publications based on HST data should carry the following footnote:
Based on observations made with the NASA/ESA Hubble Space Telescope, obtained from the data archive at the Space Telescope Institute. STScI is operated by the association of Universities for Research in Astronomy, Inc. under the NASA contract NAS 5-26555.
Publication prints
One preprint or reprint of each refereed publication based on HST archival research must be sent to the following address:
Librarian - Space Telescope Science Institute - 3700 San Martin Drive - Baltimore, Maryland 21218 USA
About this interface
This webinterface was developed at the ST-ECF using a number of toolkits. The main building blocks are:
The JavaScript/XSLT VOTable viewer originally written by R. White at STScI in the version released by T. McGlynn (sview)
Supported browsers
This interface has been successfully tested with
Mozilla Firefox 2.0+
Safari 3.3+
Opera 10.5
Google Chrome 3.0+
Internet Explorer 8
Note that the interface does not work with the Konqueror browser as this has no XSLT support and that the interface might (partly) work also with older browser versions but not with older versions of Opera or Internet Explorer.
These are the operators that are available for querying in the fields of the two interfaces, the One-line interface just below and the Form interface at the bottom.

Units
For the Form interface, the units of numerical fields are fixed and specified in the tooltip help of the fields.
For the One-line interface, units have to be given. For each type of numerical input, different units can be chosen:
Wavelength / Bandwidth / Spectral resolution
angstrom nm um
Exposure Time
sec min hour
Search box
arcsec arcmin deg
Resolution / Pixel scale
arcsec
Programmatic access
The metadata tables in the database can also be accessed programmatically e.g. from
scripts. The resulting table is written out in VOTable format which is based on xml.
