The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding. Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
Some important notes on this object about identifications and objects associations. notes: in ClG 1409+5226 The X-ray source 1RXS J141121.2+521250 was identified with the active galaxy nucleus SDSS J141120.52+521209.8 by Anderson et al. (2007AJ....133..313A). According to Flesch (2013PASA...30....4F), the position of the AGN [VV2010c] J141120.5+521110 in Veron-Cetty and Veron (2010A&A...518A..10V) is 60" off; the correct position would be 14 11 20.4 +52 12 10.

• There is a misprint leading to a 1 arcminute error in declination of [VV2010c] J141120.5+521110 of Veron-Cetty and Veron (2010A&A...518A..10V). So [VV2010c] J141120.6+521209 and [VV2010c] J141120.5+521110 are the same object.
