Abstract Service Postional Search -- Search for papers by position.

Position searches locate all objects within the specified radius of the specified position. They currently work only for the SIMBAD database. The syntax for position searches is:

right ascension ±declination: radius

All three values can be either decimal degrees or degrees, minutes (and optionally seconds) separated by a space. The plus or minus sign before the declination value is mandatory. The default for the search radius is 10 arcmin (represented as "0 10" if using degrees, minutes, seconds, or 0.16667 if using degrees).

Enter position in the object search box on the main query page.
