O/2 Extract from Ned database ================================================================================ Extract from Ned database ================================================================================ ADC_Keywords: Cross identifications ; Fundamental catalog ; Galaxy catalogs Description: 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's data and references are being continually updated, with revised versions being put on-line every 2-3 months. NED is an extragalactic database. Data and references for Galactic objects may be retrieved from SIMBAD (Set of Identifications, Measurements, and Bibliography for Astronomical Data), maintained by Centre de Donnees Astronomiques de Strasbourg, France. Similarly, solar system and planetary data (e.g. for Mars or for Halley's Comet) may be retrieved from NASA's Planetary Data System (PDS) at JPL. Many of the individual catalogues loaded into NED are available from NASA's Astronomical Data Center at the Goddard Space Flight Center, Greenbelt, Maryland, USA.
