Acknowledgement for publications
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.
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.
One preprint or reprint of each refereed publication based on HST archival research must be sent to the following address:

About this interface
This webinterface was developed at the ESA/ST-ECF using a number of toolkits. The main building blocks are:
This interface has been successfully tested with
Mozilla Firefox 2.0+
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. Additional search help is available here.
Less or equal
Greater or equal
= (case sensitive)
Exactly equal (no wildcards)
="^...$" (escape wildcards)
== (case sensitive)
Not exactly equal (no wildcards)
Wildcard: any text
Wildcard: any character
\* / \?
[*] / [?]
not / -
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
sec min hour
arcsec arcmin deg
Resolution / Pixel scale
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.
