Search Options

There are different ways to search the Hubble Data Archive (HDA), and various types of searches that can be performed. The HDA can be searched using a World Wide Web (WWW) interface and StarView, an astronomical database browser and research analysis tool. Users can also search the Archived Exposures Catalog (AEC), an ASCII listing compiled from the Hubble Space Telescope archive database. Searches can be done on object name, position, or a variety of observational parameters. Proposal numbers, proposal abstracts, and dataset names can also be searched on. Finally, various astronomical catalogs can be correlated with the HDA, to look for HST data for classes of sources.

We list below the various search options. Note FOS users should also visit the FOS POA site for the latest FOS information (the STScI pages are seriously out of date).

Search the Archive through the World Wide Web

Form Help Description
Science Search * This form lets you search the Archive on object name or position, proposal, wavelength, or instrument. You may then mark and retrieve this data from the Archive. Both public and proprietary science data may be retrieved through this form.
Science Search using a list of targets or coordinates * This form lets you search the Archive using a list of targets or coordinates as input. The uploaded file can be simply a list of (delimited) target names or coordinates, or a multi-column table.
Target Descriptions   This is a list of all the HST target descriptions currently in use, showing you which instruments have been used for each description. You can click on the instruments to get a listing of datasets for that target description.
Proposal Search * In this form, you can bring up information about a specific proposal (title, principal investigator, abstract, published papers, etc.), along with a listing of data archived for that proposal. You can also look up individual obsets (visits) for a given proposal. Both public and proprietary science data may be retrieved through this form.
Abstract Search * Search the texts of HST proposal abstracts and or proposal title, primary investigator name and proposal id with this form.
Retrieve a List
of Datasets
* If you have a list of dataset names you want to retrieve, you can enter them in this form. Or, if your browser can do a file upload, you can upload a file of dataset names. (This form is very cut-and-paste friendly: it can extract HST data set names out of mail messages, paragraphs of text, etc.)
Cross-Correlation
  Upload your own list of targets and cross-correlate it with HST, IUE, or EUVE. Or use, for example, our online AGN catalog.
Parallels   This page information and links concerning the HST Archival Pure Parallels
Duplication Checking * Use this form to check for possible duplications with your HST proposal.


Search the Archive using StarView

StarView is is an astronomical database browser and research analysis tool. Developed in Java, StarView provides an easy to use, highly capable user interface that runs on any Java enabled platform as a standalone application. StarView can be installed on Unix, Windows, and Macintosh platforms. Although the WWW interface is more convenient to use, as it does not require client-server software installation and can be accessed by any WWW browser, it does not provide all the functions of StarView as regards HST data.


The Archived Exposures Catalog

The Archived Exposures Catalog (AEC) is a flat ASCII file version of the HDA catalog. One can scan through it with a text editor or other text-handling tools. The AEC provides only limited information about HST data (and no retrieval options!). Much more information is available through StarView or the WWW interface.

Please note:The archive guest account has been discontinued,
so it will no longer be possible to run StarView on the archive host machines.
