The NASA/IPAC Extragalactic Database (NED) is built around a master list of extragalactic objects for which cross-identifications of names have been established, accurate positions and redshifts entered to the extent possible, and some basic data collected. Bibliographic references relevant to individual objects have been compiled, and abstracts of extragalactic interest are kept on line. Detailed and referenced photometry, position, and redshift data, have been taken from large compilations and from the literature. NED also includes images for over 700,000 extragalactic objects from 2MASS, from the literature, and from the Digitized Sky Survey. NED's data and references are being continually updated, with revised versions being put on-line every 2-3 months.

The returnMode parameter controls whether the results are returned in basic HTML form, as a finalInventory in XML, as a set of updateMessages, run in the background, or were one specific datafile is sent back as the response. For this service, the available datafiles are: index.html, inventory.xml, ned.tbl or ned.xml (the first two overlap with the HTML and finalInventory return modes.

For direct Oasis use, the datafile/ned.tbl return mode should be used.
