To search for NED objects and unprocessed catalog sources, enter the RA, Dec, and search radius (arcmin), then click the GO button. Ecliptic, Galactic, or Supergalactic coordinates may be entered by selecting the coordinate system (default Equatorial). The equinox of the coordinate system may also be selected (default J2000). The output coordinates will be in the same system and equinox as the input coordinates. Search results will be presented in a table, with up to 100 objects or sources per page. Placing the cursor over a table column heading will give a brief definition of its meaning. To exclude unprocessed catalog sources from the search, check the Exclude Sources box.
