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!).

Hierarchy : number of linked objects whatever the membership probability is (see description here ) : The count displayed here is the number of children objects. The list obtained by clicking the button may be larger, as some children may be linked with different references or probability. %This number is the number of distinct objets linked, by using this button, you will obtain all links (may be more than one) from that object to his children : 5539 Display criteria : All >=90% stars galaxies radio IR <2 arcsec #ref>50
